Why Your Arbeitsvertrag Matters More Than You Think
In Germany, employment law strongly protects workers — but only if your contract is fair. A poorly written or exploitative Arbeitsvertrag (employment contract) can cost you thousands in unpaid overtime, lock you into a bad job, or leave you vulnerable during probation.
Here are the red flags every expat should check before signing.
Red Flag 1: Probation Period Traps (Probezeit)
What Is Normal
Standard Probezeit: 6 months (the legal maximum)
During probation, either party can terminate with 2 weeks' notice
After probation, the standard notice period is 4 weeks to the 15th or end of the monthRed Flags
Probezeit longer than 6 months: Illegal. Any probation period exceeding 6 months is void under Section 622(3) BGB
Extended "evaluation period" disguised as probation: Some contracts add a clause like "performance review at 12 months" that effectively extends probation. This is not probation, but watch for language that ties your position to passing this review
No clear end date for probation: The contract must specify when Probezeit endsWhat to Check
Confirm that after 6 months, you receive full termination protection under the Kuendigungsschutzgesetz (if your company has more than 10 employees).
Red Flag 2: Unpaid Overtime Clauses (Ueberstunden)
What Is Normal
Overtime should be documented and compensated — either paid or offset with time-off (Freizeitausgleich)
Many contracts specify a reasonable number of overtime hours included in salary (e.g., 5-10 hours/month for managerial roles)Red Flags
"Alle Ueberstunden sind mit dem Gehalt abgegolten" (all overtime is included in the salary): Courts have repeatedly ruled this is invalid if the number of hours is not specified. Without a cap, this clause is unenforceable
No overtime documentation requirement: If the contract does not mention how overtime is tracked, insist on clarity
Unreasonable overtime expectations: More than 10 hours/week of regular overtime without additional compensation is a major red flagGerman Law Says
The Arbeitszeitgesetz (Working Time Act) limits regular working hours to
8 hours per day, extendable to 10 hours only if the average over 6 months stays at 8 hours. Anything beyond this is illegal.
Red Flag 3: Non-Compete Clauses (Wettbewerbsverbot)
What Is Normal
Post-employment non-compete (nachvertragliches Wettbewerbsverbot) is allowed for up to 2 years
The employer must pay compensation of at least 50% of your last salary for the duration of the non-compete (Karenzentschaedigung)Red Flags
Non-compete without compensation: Completely unenforceable — but it may still intimidate uninformed employees
Excessively broad scope: A non-compete covering "any company in the technology sector worldwide" is likely invalid due to unreasonable scope
Non-compete during employment that extends beyond your job duties: During employment, you cannot compete directly, but you can work on unrelated side projects unless explicitly restrictedWhat to Do
If a non-compete clause exists, check for the Karenzentschaedigung. If it is missing or below 50%, the clause is void. You can ignore it after leaving — but get legal advice to be safe.
Red Flag 4: Fixed-Term Contracts (Befristung)
What Is Normal
Fixed-term contracts (befristete Arbeitsvertraege) are common for initial employment
Maximum duration: 2 years without a specific reason (sachgrundlose Befristung)
Can be renewed up to 3 times within those 2 years
With a specific reason (Sachgrund), such as project work or parental leave replacement, there is no maximum durationRed Flags
Chain of fixed-term contracts: If you have worked for the same employer before (even years ago), a new fixed-term contract without reason may be invalid
Befristung combined with Probezeit: While legal, a 6-month fixed-term contract with a 6-month probation period means you have zero job security for the entire duration
Verbal promises of extension: "We always extend" is meaningless. If the contract ends, it ends — and you have no claim to extension or severanceImportant Rule
If you continue working after a fixed-term contract expires
without a signed extension, the contract automatically becomes
permanent (unbefristet) under Section 15(6) TzBfG. Do not let your employer pressure you into working informally.
Red Flag 5: Vacation Day Minimums (Urlaubsanspruch)
What Is Normal
Legal minimum: 20 days for a 5-day work week (24 days for a 6-day week)
Most German employers offer 25-30 days
Vacation must be taken in the calendar year; carryover is limited to March 31 of the next yearRed Flags
Exactly 20 days: While legal, this is below market standard and may indicate a cost-cutting employer
"Vacation includes public holidays": Illegal. Public holidays (Feiertage) are separate from your Urlaubsanspruch
Forced vacation during company closure (Betriebsferien): Legal, but must be announced well in advance and cannot consume all your vacation daysOther Clauses to Watch
Geheimhaltungspflicht (Confidentiality)
Reasonable confidentiality is standard. But watch for clauses that restrict you from discussing your salary — salary secrecy clauses are increasingly viewed as unenforceable in Germany.
Versetzungsklausel (Transfer Clause)
A clause allowing the employer to transfer you to a different city or role. Check how broad it is — "anywhere in Germany" is very different from "within the Munich metropolitan area."
Verfall-/Ausschlussklauseln (Forfeiture Clauses)
Clauses that void your claims (e.g., for unpaid overtime) if not asserted within 3 months. These are common but invalid if the deadline is shorter than 3 months or if they cover minimum wage claims.
