Probezeit in Hamburg: The Two-Week Notice, the Ten-Employee Line, and the City's Thousands of Small Kleinbetriebe

The Official Rule

Almost every German employment contract includes a Probezeit, a probation period, and understanding what it actually changes matters more than the label itself suggests. Under Section 622 Abs. 3 BGB, an agreed probation period can run up to six months, not longer, and during it, either you or your employer can end the contract with just two weeks’ notice, no justification required. That two-week window runs strictly day to day rather than landing on a fixed date the way the post-probation notice period does, so a termination letter can arrive on essentially any calendar day.

What actually matters more than the Probezeit label is a separate legal switch entirely: the Kündigungsschutzgesetz (KSchG), Germany’s real dismissal protection law. Two conditions both have to be true before it applies to you at all. First, you need six months of continuous employment at the same employer. Second, Section 23 KSchG requires that employer to regularly employ more than 10 people, counting part-time staff at a reduced 0.5 or 0.75 weight and excluding apprentices from the headcount entirely. Miss either condition and the detailed, socially-reasoned dismissal protections most people associate with German labor law simply don’t apply to your situation, not during probation, and in a genuinely small business, not afterward either. Handelskammer Hamburg’s own guidance confirms this is the exact framework Hamburg employers work under too, since it’s federal law with no regional variation.

One protection cuts straight through all of the above, regardless of your tenure or your employer’s size. Section 17 MuSchG bars dismissal outright from the start of a pregnancy through four months after giving birth. This isn’t a softer version of the usual rule, it overrides the simplified two-week Probezeit dismissal and the Kleinbetrieb exemption alike. A dismissal in that window is only even theoretically possible with a state labor authority’s explicit prior approval, a genuinely high bar that’s rarely cleared.

Hamburg’s Own Employer Landscape: Anchors on One Side, Thousands of Small Businesses on the Other

None of the mechanics above are Hamburg-specific, they’re federal law and apply the same way in Flensburg or Freiburg. What genuinely differs in Hamburg is the shape of its own job market: a cluster of very large, easily-over-10-employee anchor employers, and, running alongside them, a genuinely enormous layer of small, individually run businesses.

On the anchor side, Hamburg’s port, aviation and media industries dominate. HHLA employs 3,669 people in Germany across three of the port’s four container terminals, Hapag-Lloyd, one of the world’s largest container shipping lines headquartered on the Ballindamm, has close to 17,000 employees worldwide. Hamburg Aviation e.V. confirms Hamburg is the world’s third-largest civil aviation center, with Airbus employing up to 18,000 people across Finkenwerder, Stade and Buxtehude and Lufthansa Technik, the global MRO market leader, employing over 8,000 people on-site. NDR, Der Spiegel and RTL Deutschland’s roughly 1,500-person Hamburg hub anchor the city’s self-branded status as Germany’s media capital. A regular Arbeitnehmer hired at any of these organizations clears the 10-employee KSchG threshold without a second thought.

What that anchor-employer picture hides is how much of Hamburg’s actual day-to-day economy runs on businesses far smaller than that. DEHOGA Hamburg’s own figures, current as of September 2025, count 7,818 businesses in the city’s broader tourism sector, with gastronomy alone accounting for more than 5,400 of them, spread across roughly 90,000 jobs citywide in hospitality and tourism combined. That’s an average nowhere close to the size of an HHLA or an Airbus, and a large share of Hamburg’s individually owned restaurants, cafés, bars and small hotels sit at or under the 10-employee headcount the Kleinbetriebsklausel is built around.

This is exactly the population for whom “wait until KSchG kicks in” is misleading advice. At a genuine Kleinbetrieb, KSchG protection never kicks in regardless of tenure, and Hamburg’s hospitality and tourism sector, alongside the many small retail shops and trades businesses that don’t make headlines the way the port or Airbus do, has an outsized share of employers in that category.

Even Without KSchG, the Three-Week Clock Still Runs

This is the detail that catches even people who’ve correctly understood everything above. Section 4 KSchG requires anyone who wants to argue a dismissal is invalid to file suit at the Arbeitsgericht within three weeks of receiving the written notice, and its wording covers two separate grounds at once: that the dismissal is “sozial ungerechtfertigt” (socially unjustified, the standard KSchG test) “oder aus anderen Gründen rechtsunwirksam ist” (or invalid for other reasons). That second clause matters enormously in exactly the Probezeit and Kleinbetrieb situations common in Hamburg’s hospitality sector, where the first clause simply doesn’t apply.

“Other reasons” reaches genuinely common scenarios: a dismissal motivated by discrimination under the Allgemeines Gleichbehandlungsgesetz (nationality, religion, disability, age, and more), a dismissal that violates general good faith (Treu und Glauben), or retaliation for raising a legitimate complaint (Maßregelungsverbot under Section 612a BGB). None of these require six months of tenure or a large employer to invoke. What they do require is filing within the same three-week window that applies to a standard KSchG claim. Miss it, and Section 7 KSchG deems the dismissal effective from the start, regardless of how strong the underlying claim actually was.

If You Actually Need to Sue: Arbeitsgericht Hamburg

For anyone who believes a dismissal was invalid, the venue is the Arbeitsgericht Hamburg, at Osterbekstraße 96, 22083 Hamburg. Its Rechtsantragstelle, reachable at 040 42863-5820, exists specifically so that filing a Kündigungsschutzklage doesn’t require a lawyer from the outset, staff there help put the claim into the correct written form, though claims must be signed and can’t be submitted by email. Filing itself is free. The office is open Monday to Thursday from 9:00 to 15:00 and Friday from 9:00 to 14:00. The catch that trips people up is the deadline: a Kündigungsschutzklage generally has to reach the court within three weeks of receiving the written notice, and Rechtsantragstelle staff are explicitly barred from advising on whether a claim is likely to succeed, they only record what you tell them.

That gap, knowing you can file for free but not whether you should, is exactly why getting even a brief opinion from one of these advice centers, a Fachanwalt für Arbeitsrecht, or a Betriebsrat if one exists, before the three weeks run out is worth the effort.

What Real People Say

The most consistent theme across accounts from people who’ve actually gone through a German Probezeit, including a long-running Toytown Germany forum thread that’s stretched across nine pages of contributions since 2010, is genuine surprise at how little explanation a probation dismissal actually requires. People arrive expecting something closer to their home country’s process, a warning, a documented performance issue, a conversation first, and instead get a short letter and a two-week countdown with no reason stated at all, because none is legally required yet.

In Hamburg specifically, that surprise lands hardest in exactly the sector Faire Mobilität Hamburg was set up to serve: hospitality and catering, where a large share of the workforce is foreign-born and where the employer is genuinely often a small, family-run restaurant or café rather than a large company with an HR department running a documented review process in the background. The practical advice that recurs across both this group and Hamburg’s larger corporate employers is the same: find out how many people your specific employer regularly employs, not what the industry as a whole looks like, since that single number decides whether KSchG protection is even a possibility for you there.

Step by Step

1. Check your contract for the actual Probezeit length and start date, since anything past six months isn’t legally enforceable as a probation period, and the two-week notice rule only applies for as long as the agreed period actually runs.
2. Find out roughly how many people your employer regularly employs, since that number, not your job title, the size of the industry, or how long you’ve been told the role will last, decides whether KSchG protection will ever apply to you there.
3. If you work in Hamburg’s hospitality or tourism sector, treat a small headcount as the likely default, DEHOGA Hamburg’s own figures put roughly 90,000 jobs across 7,818 businesses, so many individual restaurants, cafés and small hotels sit at or under the Kleinbetrieb line.
4. If you’re dismissed and think it wasn’t about performance at all, discrimination, retaliation for a complaint, bad faith, note the date you received the written notice immediately. The three-week deadline under Section 4 KSchG to sue runs regardless of whether ordinary KSchG protection applies to you.
5. Get free advice before that deadline closes, not after. Faire Mobilität Hamburg, Arbeit und Leben Hamburg’s Servicestelle Arbeitnehmerfreizügigkeit, or DGB Rechtsschutz (if you belong to a union) can tell you quickly whether a claim is worth filing.
6. If you do need to file, the Arbeitsgericht Hamburg’s Rechtsantragstelle at Osterbekstraße 96 will record your claim without a lawyer, Monday to Thursday mornings and afternoons, Friday mornings only.
7. If you become pregnant during Probezeit, tell your employer and lean on Section 17 MuSchG specifically. It overrides the simplified dismissal rule and the Kleinbetrieb exemption alike, regardless of your tenure.

Compliance Note

This page explains the general framework around German probation periods and dismissal protection under the BGB, KSchG and MuSchG, and how Hamburg’s own mix of large anchor employers and a large hospitality sector fits into it, but this is not legal advice, and specific circumstances, your contract’s exact wording, your employer’s actual headcount, can change the outcome. For your specific situation, confirm current details with a free counseling center such as Faire Mobilität Hamburg or Arbeit und Leben Hamburg, a labor law advisor (Fachanwalt für Arbeitsrecht), or the Arbeitsgericht Hamburg directly.
