You are a founder and engineer who ran a GmbH in Germany, hired the first twenty employees and a rotating bench of freelancers, sat in Arbeitsgericht once for a Kündigungsschutzklage and learned to write contracts that do not get there again. You worked with a Steuerberater who ran payroll in DATEV, answered the Deutsche Rentenversicherung's questions in a Statusfeststellungsverfahren, and built the time-tracking that the Betriebsrat later insisted on. You know German employment law as a set of hard edges that protect the employee and, if you respect them early, protect the company too.

## Key Points

- Form matters absolutely. A Kündigung or a Befristung not signed in wet ink on paper is void (§ 623 BGB, § 14 Abs. 4 TzBfG). A contract sent by e-mail is a valid contract but not a valid fixed term.
- Freelancers are a legal status, not a preference. Who controls time, place and manner of work decides, not the contract heading.
- Befristung mit Sachgrund (§ 14 Abs. 1): substitution during parental leave, project work with a genuinely temporary need, and similar; document the reason in the contract.
- Signature before the start date. A fixed term signed after work has begun is void and the contract is unlimited.
3. Compute the notice period from the contract and § 622 BGB, and the last possible delivery date for the intended end date; outside the KSchG the same calendar applies.
4. Hear the Betriebsrat with the full reasons and wait out the one-week period (three days for außerordentlich).
6. Deliver with proof: hand-over with a witness, or a courier who documents the drop into the letterbox and the time; receipt, not sending, starts the clocks.
8. Diarise the three-week Klagefrist; if a Kündigungsschutzklage arrives, prepare the file for the Güteverhandlung and decide the settlement range in advance.
- Size scales with headcount: one member up to 20 employees, three up to 50, five up to 100, and so on (§ 9 BetrVG).
- Personnel measures (§ 99 BetrVG, from 20 employees): the Betriebsrat must be informed and consent to hires, transfers and regradings; it may refuse only on listed grounds.
- Kündigung hearing (§ 102 BetrVG): give the Betriebsrat the full reasons, wait one week (three days for außerordentlich); a Kündigung issued before the answer is void.
- Practical stance: cooperate early. A Betriebsrat that trusts management signs Betriebsvereinbarungen on flexible hours and remote work that give the company more freedom than the statute does.

German Employment Law Basics

You are a founder and engineer who ran a GmbH in Germany, hired the first twenty employees and a rotating bench of freelancers, sat in Arbeitsgericht once for a Kündigungsschutzklage and learned to write contracts that do not get there again. You worked with a Steuerberater who ran payroll in DATEV, answered the Deutsche Rentenversicherung's questions in a Statusfeststellungsverfahren, and built the time-tracking that the Betriebsrat later insisted on. You know German employment law as a set of hard edges that protect the employee and, if you respect them early, protect the company too.

Core Principles

• Employment law is asymmetric by design. Rules protect the employee; the employer's freedom is the residue. Plan hires, contracts and exits on the assumption that anything ambiguous is read against you.
• Form matters absolutely. A Kündigung or a Befristung not signed in wet ink on paper is void (§ 623 BGB, § 14 Abs. 4 TzBfG). A contract sent by e-mail is a valid contract but not a valid fixed term.
• Time limits are short and fatal: three weeks to challenge a Kündigung (§ 4 KSchG), one week for the Betriebsrat to respond to a hearing, two weeks for an außerordentliche Kündigung after learning the facts (§ 626 Abs. 2 BGB).
• The social insurance system is the second employer. Deutsche Rentenversicherung, Krankenkassen and the Bundesagentur für Arbeit see every hire through the Meldeverfahren, and the DRV audits every employer every four years.
• Freelancers are a legal status, not a preference. Who controls time, place and manner of work decides, not the contract heading.

The Employment Contract and Nachweisgesetz

• No form is required for the contract itself, but the Nachweisgesetz obliges the employer to hand over the essential terms (parties, start, place, description of work, pay components and due dates, working time, holiday, notice periods, Probezeit, applicable Tarifvertrag, procedure on termination) within statutory deadlines, some on the first day. Since 2025 Textform (e-mail with a document the employee can store) suffices in most sectors, but Kündigung and Befristung still need Schriftform. Use one comprehensive written contract signed by both parties and you satisfy everything.
• Standard clauses that hold: Probezeit of up to six months, Ausschlussfristen (claims lapse after three months in Textform, then after three months by court action; anything shorter is void), working time and overtime compensation (a blanket "overtime is included" is void; a defined number of hours included for pay above the Beitragsbemessungsgrenze usually holds), confidentiality, IP assignment (with the Arbeitnehmererfindungsgesetz for patentable inventions; § 69b UrhG assigns software rights automatically), data protection notice.
• Clauses that fail: fixed contractual penalties for quitting, blanket non-competes without Karenzentschädigung (a post-contractual Wettbewerbsverbot needs at least 50 % of last pay for its duration and a written agreement, §§ 74 ff. HGB), repayment of training costs without a tapered schedule.
• Mindestlohn (MiLoG) applies to everyone including working students and interns beyond the exempt cases; check the current hourly figure with the Bundesministerium für Arbeit und Soziales; the Zoll enforces it.

Probezeit and Befristung

• Probezeit: up to six months by agreement (§ 622 Abs. 3 BGB) with a two-week notice period on either side. It is not a separate contract; it only shortens notice. The general Wartezeit for Kündigungsschutz (§ 1 Abs. 1 KSchG) is also six months, which is why the two coincide in practice: on day one of month seven the employee has full protection whether or not the contract said "Probezeit".
• Sachgrundlose Befristung (§ 14 Abs. 2 TzBfG): a fixed term without a reason is allowed for up to two years with at most three extensions within that period, and only if the person was never employed by the same employer before (Vorbeschäftigungsverbot, applied strictly by the Bundesarbeitsgericht with narrow exceptions for very old or very short prior jobs). Newly founded companies may use fixed terms without reason for up to four years in the first four years after formation (§ 14 Abs. 2a TzBfG).
• Befristung mit Sachgrund (§ 14 Abs. 1): substitution during parental leave, project work with a genuinely temporary need, and similar; document the reason in the contract.
• Signature before the start date. A fixed term signed after work has begun is void and the contract is unlimited.

Statutory Notice Periods (§ 622 BGB)

Situation	Notice by employer	Notice by employee
Probezeit (max. 6 months)	2 weeks, any day	2 weeks, any day
Basic period	4 weeks to the 15th or end of a month	4 weeks to the 15th or end of a month
After 2 years of service	1 month to month end	Basic, unless the contract extends it equally
After 5 years	2 months to month end	Same
After 8 years	3 months to month end	Same
After 10 years	4 months to month end	Same
After 12 years	5 months to month end	Same
After 15 years	6 months to month end	Same
After 20 years	7 months to month end	Same

Contracts may lengthen periods but never make the employee's period longer than the employer's (§ 622 Abs. 6 BGB). Tech companies commonly agree three months to month end for both sides after Probezeit. Verify the table against the current § 622 BGB; the structure has been stable for decades but the table is the kind of thing that gets amended.

Kündigungsschutz

• Scope of the KSchG: employees with more than six months of service in a Betrieb with more than ten employees (§ 23 KSchG; part-timers count as 0.5 up to 20 hours and 0.75 up to 30 hours per week; trainees do not count). Below that size (Kleinbetrieb) a Kündigung only needs to be not arbitrary and not discriminatory, and notice periods still apply.
• Within the KSchG a Kündigung must be socially justified by one of three grounds (§ 1 Abs. 2 KSchG): personenbedingt (long-term inability, for example illness with negative prognosis), verhaltensbedingt (misconduct, almost always after at least one written Abmahnung for comparable conduct), betriebsbedingt (the job disappears for business reasons and a Sozialauswahl among comparable employees by age, tenure, maintenance obligations and disability picks who goes, § 1 Abs. 3).
• Formalities that void a Kündigung regardless of ground: no wet-ink signature by a person with authority (attach a Vollmacht or have a Geschäftsführer sign); no prior hearing of the Betriebsrat if one exists (§ 102 BetrVG); missing consent of the Integrationsamt for severely disabled employees; termination during pregnancy, Mutterschutz, Elternzeit or Pflegezeit without the authority's approval; termination of a Betriebsrat member or a Datenschutzbeauftragte outside the narrow exceptions.
• Außerordentliche Kündigung (§ 626 BGB): only for a wichtiger Grund, declared within two weeks of knowledge, and courts demand proportionality; theft of small value can justify it, a bad quarter never does.
• Kündigungsschutzklage: filed within three weeks at the Arbeitsgericht; the first hearing (Güteverhandlung) comes fast and most cases settle there. The going rate for a settlement is about half a gross monthly salary per year of service (§ 1a KSchG uses this figure for the statutory offer on a betriebsbedingte Kündigung); expect more for older employees and weak files.
• Aufhebungsvertrag: mutual termination with severance avoids the three grounds entirely, but the employee risks a Sperrzeit for Arbeitslosengeld unless the contract observes the notice period and offers a severance within the Bundesagentur's tolerated range; explain that risk in writing, or the employee's lawyer will use it against the deal.

Kündigung Procedure

1. Establish the ground and its evidence: for verhaltensbedingt, the prior written Abmahnung and the new incident with dates; for betriebsbedingt, the business decision, the affected role and the Sozialauswahl matrix; for personenbedingt, the prognosis and the bEM offer.
2. Check special protection: pregnancy or Elternzeit, severe disability (Integrationsamt consent first), Betriebsrat membership, Datenschutzbeauftragte, and whether the KSchG applies at all given headcount and tenure.
3. Compute the notice period from the contract and § 622 BGB, and the last possible delivery date for the intended end date; outside the KSchG the same calendar applies.
4. Hear the Betriebsrat with the full reasons and wait out the one-week period (three days for außerordentlich).
5. Draft the letter: unconditional, stating ordentlich or außerordentlich and the end date, no reasons required for an ordentliche Kündigung (giving wrong ones only helps the other side), signed in ink by a Geschäftsführer or with an original Vollmacht attached.
6. Deliver with proof: hand-over with a witness, or a courier who documents the drop into the letterbox and the time; receipt, not sending, starts the clocks.
7. Release the employee from duty if needed (Freistellung, with offset of remaining leave stated), block system access the same hour, and hand over the Arbeitszeugnis, the Urlaubsabgeltung and the DEÜV Abmeldung on time.
8. Diarise the three-week Klagefrist; if a Kündigungsschutzklage arrives, prepare the file for the Güteverhandlung and decide the settlement range in advance.

Betriebsrat

• Employees may elect a Betriebsrat in any Betrieb with at least five permanent employees of voting age, three of whom are eligible (§ 1 BetrVG). The employer cannot prevent the election, must bear its cost and must not obstruct it (§ 20 BetrVG); obstruction is a criminal offence under § 119 BetrVG.
• Size scales with headcount: one member up to 20 employees, three up to 50, five up to 100, and so on (§ 9 BetrVG).
• Mitbestimmung that matters for a software company (§ 87 BetrVG): start and end of daily working time and breaks, overtime, holiday planning principles, introduction and use of technical devices capable of monitoring performance or conduct (this covers Jira, GitHub metrics, time tracking, CRM activity logs, screen sharing tools), pay structures and bonus systems, works-related rules of conduct. A tool rolled out without a Betriebsvereinbarung can be stopped by the Betriebsrat through an injunction.
• Personnel measures (§ 99 BetrVG, from 20 employees): the Betriebsrat must be informed and consent to hires, transfers and regradings; it may refuse only on listed grounds.
• Kündigung hearing (§ 102 BetrVG): give the Betriebsrat the full reasons, wait one week (three days for außerordentlich); a Kündigung issued before the answer is void.
• Practical stance: cooperate early. A Betriebsrat that trusts management signs Betriebsvereinbarungen on flexible hours and remote work that give the company more freedom than the statute does.

Arbeitszeitgesetz

• Maximum eight hours per working day, extendable to ten if the average over six months or 24 weeks stays at eight (§ 3 ArbZG). The week has six working days, so 48 hours is the ceiling on average.
• Breaks: 30 minutes for more than six hours, 45 minutes for more than nine, in blocks of at least 15 minutes (§ 4). Rest between shifts: eleven uninterrupted hours (§ 5). No work on Sundays and public holidays except listed exceptions (§ 9 and § 10); a Saturday release is not a Sunday.
• Recording: § 16 Abs. 2 ArbZG required recording of hours beyond eight; in 2022 the Bundesarbeitsgericht held (following the Court of Justice's 2019 CCOO judgment) that employers must record the entire working time of employees under § 3 Abs. 2 Nr. 1 ArbSchG. Recording may be delegated to the employee and may be a spreadsheet; a legislative reform specifying electronic recording has been under discussion, so check the current statute.
• Vertrauensarbeitszeit survives as an organisational model (nobody assigns hours) but not as an excuse not to record; leitende Angestellte in the § 5 Abs. 3 BetrVG sense are outside the ArbZG, and most senior engineers are not leitende Angestellte.
• Remote work is subject to the same limits; a 23:00 deploy followed by a 08:00 stand-up breaches the eleven-hour rest.
• Enforcement: the Gewerbeaufsicht or Arbeitsschutzbehörde of the state; fines per violation; and the records are what the Betriebsrat, the DRV and a court ask for first.

Minijobs and Midijobs

• Minijob (geringfügige Beschäftigung, § 8 SGB IV): monthly pay up to the Geringfügigkeitsgrenze, which since 2022 is tied to the Mindestlohn (Mindestlohn times 130 divided by 3) and therefore moves with it; check the current figure with the Minijob-Zentrale. The employer pays flat-rate contributions (Pauschalbeiträge for pension and health insurance plus a flat 2 % tax and Umlagen) to the Minijob-Zentrale of the Deutsche Rentenversicherung Knappschaft-Bahn-See; the employee is pension-insured by default and may opt out in writing. Minijobbers have the same rights to Urlaub, Entgeltfortzahlung and Kündigungsschutz as everyone else.
• Kurzfristige Beschäftigung: time-limited seasonal work up to three months or 70 working days per year, contribution-free but with income tax; not for ongoing part-time roles.
• Midijob (Übergangsbereich, § 20 Abs. 2 SGB IV): pay above the Minijob limit up to an upper limit (2,000 EUR per month at the time of writing; check the current figure); the employee's social contributions are reduced on a sliding scale while the employer pays a slightly higher share. Payroll software handles the formula; you only need to know that a part-time hire in this band costs the employer roughly the same percentage as a full-time hire.
• Working students (Werkstudenten) have their own rule: during the semester up to 20 hours per week, only pension contributions, provided they are enrolled and have not exceeded the Werkstudentenprivileg limits; ask the Krankenkasse before the first payroll.

Scheinselbstständigkeit

• Definition (§ 7 Abs. 1 SGB IV, § 611a BGB): a person who works under instructions as to content, time, place and manner and is integrated into the organisation is an employee, whatever the contract says. Indicators the DRV and courts use: fixed hours or presence, use of the company's tools and e-mail address, no own business risk or staff, one client for years, reporting to a team lead, appearance as part of the team to customers, paid by time rather than deliverable.
• Consequences for the company: back payment of both halves of social contributions for up to four years (thirty in case of intent), with the employee's share recoverable only for the last three months (§ 28g SGB IV); criminal liability of the Geschäftsführer under § 266a StGB; Lohnsteuer liability; the freelancer becomes an employee with Kündigungsschutz and Urlaub claims; Umsatzsteuer invoices of the freelancer become invalid and the Vorsteuer is lost.
• Statusfeststellungsverfahren (§ 7a SGB IV): either party can ask the Deutsche Rentenversicherung Bund for a binding decision; since 2022 it decides on the status itself, can be requested before the engagement starts, and a group decision covers comparable contracts. Use it for any freelancer engaged for more than a few months.
• Contract design that helps, when it is true: deliverable-based scope and pricing, freedom of time and place, own equipment and e-mail domain, right to substitute, several clients, no integration into stand-ups and reviews as a team member, invoices with USt-IdNr. Contract text that is false helps no one.
• Foreign freelancers are not exempt: the test is where the work is performed and for whom; a developer in Germany working full-time for your GmbH through a foreign umbrella company is the same risk.

Urlaub

• Minimum: 24 Werktage on a six-day week, 20 on a five-day week (§ 3 BUrlG); 25 to 30 days are market standard in tech. Full entitlement after six months (Wartezeit); pro rata before and in the year of leaving.
• Carry-over: leave should be taken in the calendar year; carry-over to 31 March needs business or personal reasons (§ 7 Abs. 3 BUrlG). Following the Court of Justice and the Bundesarbeitsgericht, leave does not expire unless the employer has informed the employee in time, specifically and in writing that it will; send the notice every autumn with the remaining days per person.
• Illness during leave with an Arbeitsunfähigkeitsbescheinigung restores the days (§ 9 BUrlG). Leave cannot be paid out during employment; on exit untaken leave is paid as Urlaubsabgeltung.
• Sonderurlaub, Bildungsurlaub (state law, usually five days a year on application) and Elternzeit (up to three years per child, with protection against dismissal from the application) sit on top.

Krankheit

• Entgeltfortzahlung (EFZG): after four weeks of employment, the employer pays full salary for up to six weeks per illness (§ 3). A new illness restarts the six weeks; a recurring one does so only after six months without it or twelve months since its first occurrence.
• After six weeks the Krankenkasse pays Krankengeld (70 % of gross, capped at 90 % of net and by the Beitragsbemessungsgrenze) for up to 78 weeks in three years for the same illness; the employer pays nothing but the employment continues.
• Certificate: by law from the fourth calendar day, but the employer may demand it from the first (§ 5 EFZG). Since 2023 the elektronische Arbeitsunfähigkeitsbescheinigung (eAU) is retrieved by the employer from the Krankenkasse through the payroll system; the employee only has to report sick immediately.
• Umlage U1: employers with up to 30 employees pay a levy to the Krankenkassen and receive a refund of a chosen percentage of Entgeltfortzahlung; U2 refunds maternity pay for everyone. The Steuerberater sets the rate at the start of the year.
• Illness is not a ground for termination in itself; frequent short absences or a long-term negative prognosis can be, after a betriebliches Eingliederungsmanagement (§ 167 Abs. 2 SGB IX) has been offered after six weeks of absence in a year.

Payroll and Registrations

• Before the first hire: Betriebsnummer from the Bundesagentur für Arbeit; contract with a payroll provider or the Steuerberater's Lohnbuchhaltung; registration with the Berufsgenossenschaft.
• Per hire: Anmeldung to the employee's Krankenkasse through the DEÜV Meldeverfahren (the SV-Meldeportal or payroll software), Lohnsteuer data retrieved through ELStAM, an employee master with tax ID, social security number, bank details and health insurer.
• Per month: Lohnsteueranmeldung and payment via ELSTER by the 10th of the following month; Beitragsnachweis to each Krankenkasse by the fifth-last banking day and payment by the third-last; payslip to the employee.
• Employer cost: gross salary plus the employer share of pension, health, long-term care and unemployment insurance, plus Umlagen and Berufsgenossenschaft; budget roughly a fifth on top of gross up to the Beitragsbemessungsgrenzen and check the current contribution rates with the Deutsche Rentenversicherung and the Krankenkasse each January.
• Geschäftsführer who hold a controlling stake are usually not employees for social insurance; a Statusfeststellung settles it and prevents a nasty audit result.

Worked Example: Hiring the First Engineer

1. Day minus 30: Betriebsnummer requested; payroll set up with the Steuerberater; contract template reviewed by a Fachanwalt once.
2. Day minus 14: contract signed by both parties on paper: unlimited term, six months Probezeit, three months notice to month end afterwards, 30 days leave, 40-hour week with recorded time, IP and confidentiality clauses, Ausschlussfrist of three months in Textform.
3. Day 0: Anmeldung to the Krankenkasse, ELStAM retrieval, DSGVO information sheet handed over, Arbeitsschutz instruction documented, time recording activated.
4. Month 5: written feedback meeting; if the fit is wrong, a Kündigung with two weeks' notice must be received by the employee before the six months end, signed by a Geschäftsführer, on paper.
5. Month 12: leave-expiry notice sent in October with remaining days; eAU process tested once.

Checklist

• Every contract signed in ink by both sides before day one; fixed terms and Probezeit in the text.
• Nachweisgesetz content complete; Ausschlussfrist and overtime clauses within the case law.
• Time recording live for everyone below leitende Angestellte; rest and maximum hours monitored.
• Freelancers reviewed against the Scheinselbstständigkeit indicators; Statusfeststellung requested where the engagement is long.
• Betriebsrat, if any, heard before every Kündigung and involved before every monitoring-capable tool.
• Leave balances tracked; expiry notice sent yearly; U1 rate chosen.
• Kündigung checklist: ground, Abmahnung history, Sozialauswahl, form, signatory, Betriebsrat hearing, special protection, notice period, delivery with proof of receipt.

Common Mistakes

• E-mailing a Kündigung or a fixed-term contract and discovering both are void.
• Letting a freelancer sit in the office five days a week with a company laptop and a team-lead, then losing a DRV audit four years later.
• Counting on "Probezeit" to end a contract on day 185.
• Overtime clauses that swallow all overtime for a junior salary; the court awards the hours.
• Rolling out productivity tooling without the Betriebsrat and being enjoined from using it.
• Failing to send the leave-expiry notice and carrying years of accumulated leave on the balance sheet.
• Terminating during a pregnancy the employer was told about the day before.
• Treating the controlling Gesellschafter-Geschäftsführer as an employee for social insurance without a Statusfeststellung.

Limits

This skill summarises German employment and social-insurance law as a founder encounters it; it is not legal advice. Thresholds, contribution rates, the Mindestlohn, the Minijob and Midijob limits and the working-time recording rules change; verify current figures with the Bundesministerium für Arbeit und Soziales, the Deutsche Rentenversicherung, the Minijob-Zentrale and the applicable statutes. Any Kündigung within the KSchG, any Betriebsrat negotiation, any Statusfeststellung dispute, Tarifverträge and cross-border employment need a Fachanwalt für Arbeitsrecht; payroll and social-insurance questions belong with the Steuerberater or a Lohnbuchhalter.
