Arbeitsvertrag — Employment Contract under § 611a BGB

The Arbeitsvertrag — the German employment contract — is the contractual home for any relationship in which a person performs work in personal subordination, integrated into the work organisation of another, and bound by instructions as to time, place and content. It is the dominant labour-law instrument for the German economy, and its drafting is hemmed in by an unusually dense network of protective statutes: the § 611a BGB definition of the employment relationship, the Nachweisgesetz catalogue of essential terms that must be evidenced in writing, the Kündigungsschutzgesetz regime against socially unjustified dismissal, the Bundesurlaubsgesetz minimum-vacation floor, the § 622 BGB escalating notice periods, and the absolute Schriftform mandate of § 623 BGB for any termination. None of these can be contracted around to the disadvantage of the employee. This page is the drafting reference for the contract type.

Applicable Law

The civil-law foundation is § 611a BGB, introduced in April 2017 to codify decades of BAG case law on the Arbeitsverhältnis. Subsection 1 defines the employment contract as a Dienstvertrag whose content obliges the worker to render services in persönlicher Abhängigkeit — personal dependence — for another. The statute lists the indicia: the worker performs weisungsgebundene, externally determined work, integrated into a foreign work organisation, with Weisungsrecht covering content, performance, time, duration and place of the activity. The Gesamtbetrachtung — total-circumstances assessment — controls; the contract title does not. A document captioned Freier-Mitarbeiter-Vertrag whose substance shows fixed working hours, integration into team workflows, mandatory attendance at internal meetings and exclusivity is an Arbeitsvertrag, with all the social-security and labour-law consequences that flow from that classification. The fixed-term variant runs through § 14 TzBfG: a Befristung requires either an objective justifying ground (Sachgrund — project work, parental-leave cover, probationary need beyond the regular probation, fixed-budget engagement) or, in its absence, falls within the sachgrundlose ceiling of two years and a maximum of three extensions, with a strict bar on chain contracts. The KSchG protective regime kicks in once the employment has run for more than six months and the employer regularly employs more than ten full-time-equivalent staff: from that threshold onward, ordinary dismissal requires soziale Rechtfertigung on personal, conduct-related or operational grounds, and the burden of proof is on the employer.

Form Requirements

Two distinct rules apply, and they are routinely confused. The Arbeitsvertrag itself is not subject to a statutory form requirement: the parties can conclude an employment relationship orally or by conclusive conduct. Textform in the sense of § 126b BGB — including a plain email exchange or a digitally signed PDF — is sufficient between the parties as a matter of contract formation. The Nachweisgesetz, however, layers a parallel evidentiary obligation on top: under § 2 NachwG, the employer must record the essential terms of the contract and provide the worker with a signed copy. Until 2022, this required Schriftform under § 126 BGB — a handwritten signature on paper. The amendment that took effect on 1 August 2022 transposed the EU Working Conditions Directive and tightened the catalogue but kept the strict form: the law continues to read in Schriftform, with electronic form expressly excluded by § 2 Abs. 1 Satz 3 NachwG. A digitally signed Nachweis is therefore non-compliant for these terms even if the underlying employment contract is itself perfectly valid in Textform. Where the employer wishes a fully digital workflow for the Nachweis obligation, the only path that preserves evidentiary value is a qualified electronic signature under § 126a BGB on a wet-ink-equivalent basis, but even that does not cure the express NachwG carve-out — the wet-ink original remains the safe path. The form rule for termination is categorical and applies regardless of any electronic-onboarding regime: § 623 BGB prescribes Schriftform for any Kündigung and any Aufhebungsvertrag, and § 623 Satz 2 expressly excludes electronic form. Textform is not sufficient. A termination by email, by Slack message, by simple PDF, or even by an ordinary electronic signature is nichtig under § 125 BGB — without legal effect. The rare path that survives § 623 BGB is a qualified electronic signature on a stand-alone declaration where both parties have voluntarily opted in; the safer practice in industry remains a wet-ink original delivered in person or by registered post.

Required Clauses

The list of clauses that the employment contract — or, more precisely, the § 2 NachwG Nachweis — must record is statutory. Since the August 2022 amendment, the catalogue runs to roughly fifteen items, and an employer who omits any of them is liable to a Bußgeld of up to two thousand euros per violation. The recurring core is the following.

Vertragsparteien. Full legal names and addresses of employer and employee. For corporate employers, the Sitz and registry data; for individual employees, the residential address.

Beginn des Arbeitsverhältnisses. The start date. For fixed-term contracts, the agreed end date and either the Sachgrund or the sachgrundlose-Befristung characterisation under § 14 TzBfG.

Arbeitsort. The place of work. Where the worker has no fixed place of work or can be deployed at multiple locations, an explicit notice that the worker can be required to work at different places must be included.

Tätigkeitsbezeichnung und Tätigkeitsbeschreibung. Job title plus a description of the activities owed. The level of detail must be sufficient to identify the vertragsgemäße Tätigkeit — the activity for which the worker can be assigned without the employer needing a Versetzung under § 106 GewO.

Vergütung. The composition of remuneration: base salary, allowances, bonuses, supplements for overtime, night work, Sundays and public holidays, the cycle of payment and the means of payment.

Arbeitszeit. Agreed working time. Statutory ceiling under Arbeitszeitgesetz is eight hours per working day, extendable to ten if the average over six months stays at eight; rest-period and Sunday/public-holiday rules apply.

Urlaub. Annual vacation entitlement. The Bundesurlaubsgesetz sets the floor at twenty-four working days per year on a six-day-week basis, twenty days on a five-day-week basis. Most market contracts run between twenty-five and thirty working days on a five-day basis. Vacation accrues during probation and rolls into the calendar year mechanism in the second half of the first year.

Kündigungsfristen. A reference to the applicable statutory or contractual notice period under § 622 BGB. Where an applicable collective agreement modifies these, the reference is made to the Tarifvertrag.

Tarifvertrag, Betriebs- oder Dienstvereinbarung. Any collective agreement, works-council agreement or service agreement that applies to the relationship must be named. Omission triggers the § 2 NachwG penalty and creates an evidentiary gap that the BAG resolves in favour of the worker on the disputed term.

Optional and Recommended Clauses

Beyond the NachwG core, several clauses are not statutorily mandatory but are commercially essential.

Probezeit. § 622 Abs. 3 BGB authorises a probationary period of up to six months during which the notice period for either side is reduced to two weeks. A probation longer than six months is invalid as a probation under § 622 Abs. 3 BGB and reverts to ordinary notice from the start, although the BAG recognises distinct erweiterte Probezeit arrangements where the parties extend ordinary notice beyond two weeks but mark a longer period for performance assessment without reducing notice further.

Nachvertragliches Wettbewerbsverbot. A post-contractual non-compete is permissible under § 74 HGB and §§ 74 ff. HGB applied by analogy to non-merchant employees. Mandatory features: maximum two-year duration, scope limited to the employer’s legitimate protective interest, and a Karenzentschädigung of at least fifty per cent of the worker’s last contractual remuneration for each month of the restraint. Without compensation, the clause is unverbindlich — the employee can choose to honour it (and claim compensation) or disregard it.

Verschwiegenheitspflicht. Confidentiality during and after employment. Cross-link to /handbook/de/contracts/nda.html for the stand-alone NDA reference.

Erfindungen und Schutzrechte. Employee inventions are governed by the Arbeitnehmererfindungsgesetz (ArbnErfG). The contract usually re-states the statutory framework: the employee must report a Diensterfindung immediately, the employer can claim it within four months, and a remuneration is owed under the formula in the Vergütungsrichtlinien. For non-patentable copyrightable work product (software, design, written work), the contract should grant the employer an exclusive, transferable, sub-licensable right of use covering all known and currently unknown forms of exploitation.

Mobile Arbeit / Homeoffice. No statutory entitlement, but practice has converged on an explicit clause specifying available working locations, equipment provision, expense allocation and the employer’s right of revocation on reasonable notice.

Aufwendungsersatz. Travel, equipment and professional-association expenses, with documentation standards and a pre-approval mechanism for non-routine items.

Prohibited Clauses (in AGB Context)

Most employment contracts are AGB — pre-formulated, intended for multiple use, and unilaterally imposed by the employer — so the §§ 305-310 BGB control regime applies on top of the labour-law statutes. Three patterns are routinely struck down.

Erosion der KSchG-, BUrlG- oder § 622-BGB-Mindeststandards. Any clause that purports to lower the BUrlG vacation minimum, shorten the § 622 statutory notice below the floor, or limit the KSchG protective regime beyond what the statute allows is unwirksam under § 307 BGB as an unreasonable disadvantage; in many cases it is also void by direct operation of the relevant labour statute, which is einseitig zwingend — protective in favour of the employee.

Verlängerung der Probezeit über sechs Monate. A clause that extends the probationary period beyond six months in the § 622 Abs. 3 BGB sense — i.e. with the reduced two-week notice — is invalid; the period reverts to ordinary § 622 notice from the seventh month at the latest. The BAG has emphasised that the protective rationale of the six-month ceiling cannot be circumvented by labelling.

§ 309 Nr. 8 BGB — Pflichtverletzung-Klauseln. § 309 Nr. 8 BGB flatly voids a range of liability and warranty clauses in AGB, including any clause that excludes or limits the employer’s liability for damage caused by breach of duty in cases beyond the narrow exceptions the statute permits. While § 309 BGB applies most directly to consumer contracts, the BGH and BAG apply its rules through § 307 BGB Indizwirkung in the employment context: the same patterns are unreasonably disadvantageous to the employee and fall. Liability shift clauses requiring the employee to bear damage caused by ordinary negligence in normal work performance are read down under the BAG innerbetrieblicher Schadensausgleich doctrine: the employee bears no liability for leichteste Fahrlässigkeit, partial liability for mittlere Fahrlässigkeit, and full liability only for grobe Fahrlässigkeit and Vorsatz — and only within the limits of proportionality.

Termination and Notice

Three regimes interlock. Default ordentliche Kündigung runs on the § 622 BGB escalating timetable. The basic period is four weeks to the fifteenth or to the end of a calendar month. From the second year of employment onward the period extends in steps: one month to the end of the calendar month after two years, two months after five years, three months after eight years, four months after ten years, five months after twelve years, six months after fifteen years, and seven months to the end of the calendar quarter after twenty years. The escalating periods bind the employer; the employee owes only the basic four-week notice unless the contract says otherwise. Außerordentliche Kündigung aus wichtigem Grund under § 626 BGB is available where the Gesamtbetrachtung shows that the terminating party cannot reasonably be expected to continue the relationship up to ordinary notice end, and must be exercised within two weeks of knowledge of the underlying facts. The KSchG protective regime applies once the threshold of six months tenure plus more than ten regular employees is crossed: from then on, an ordinary termination by the employer requires soziale Rechtfertigung on personal, conduct-related or operational grounds, and the Sozialauswahl — selection on the basis of length of service, age, dependants and disability — applies in operational redundancies. Mass-layoff thresholds under § 17 KSchG trigger Massenentlassungsanzeige obligations to the Bundesagentur für Arbeit and consultation with the works council, with a Sozialplan mechanism to allocate severance. The Schriftform mandate of § 623 BGB overlays all of this: any termination, by either side, must be in handwritten Schriftform. Electronic termination is excluded by § 623 Satz 2 BGB, and a Schriftformverstoss makes the termination nichtig under § 125 BGB — the employment continues, the employee can claim Annahmeverzugslohn for the period the employer wrongly treated as terminated, and the employer must restart the process with a compliant declaration.

Court Precedent

BAG 9 AZR 162/19 (2019) addressed the limits of the probationary-period rule under § 622 Abs. 3 BGB. The decision confirmed that any contractual extension of the probation past six months in the sense of the reduced two-week notice is invalid, and that an extension agreed at the end of an initial six-month probation cannot be smuggled in through linguistic sleight: the protective rationale of the six-month ceiling controls, regardless of how the parties label the longer period. Drafting that wishes to retain a longer performance-assessment window must use a separate mechanism that preserves ordinary § 622 notice from month seven onward.

BAG 2 AZR 600/14 (2015) is the leading post-codification authority on Schriftformverstoss under § 623 BGB. The court held that a termination not satisfying the handwritten-signature requirement is nichtig and produces no legal effect; the employment continues unaltered, and the worker is entitled to Annahmeverzugslohn under § 615 BGB for the period the employer treated as terminated. The decision underscores that Textform — including unqualified electronic signatures and email — is not a substitute, and that even an Aufhebungsvertrag concluded by the parties together must satisfy § 623 BGB to be effective.

Common Pitfalls

Six recurring failure modes deserve flagging. First, Scheinselbständigkeit travelling in the opposite direction: a contract drafted as a freier Mitarbeitervertrag whose substance is an Arbeitsverhältnis triggers reclassification, backdated social-security contributions for up to four years, exposure under § 266a StGB Vorenthalten und Veruntreuen von Arbeitsentgelt for the principal, and KSchG protection retroactive to the start of the relationship. Cross-link to /handbook/de/contracts/dienstvertrag.html for the Dienstvertrag-side counterpart of the analysis. Second, attempted electronic Aufhebungsvertrag without QES: § 623 BGB does not allow Textform, so a separation agreement signed by DocuSign-style electronic signature is nichtig and the employment continues. Third, missing or incomplete Tarifvertrag reference: the § 2 NachwG penalty plus an evidentiary gap that the BAG closes against the employer on the contested term. Fourth, post-contractual non-compete without Karenzentschädigung: unverbindlich under § 74 HGB applied by analogy, leaving the employee free to disregard the restraint, and leaving the employer with no enforcement mechanism even where the substantive restraint would have been valid with compensation. Fifth, attempted probation extension past six months: invalid under § 622 Abs. 3 BGB, with the reduced notice falling away and KSchG protection accelerating. Sixth, AGB-style liability shift onto the employee for ordinary negligence: read down under the BAG innerbetrieblicher Schadensausgleich doctrine and § 307 BGB, leaving the employer with the leichteste Fahrlässigkeit exposure regardless of clause language.

The integrating discipline is recognising that the Arbeitsvertrag sits at the intersection of contract law and protective labour law, and that the protective layer is einseitig zwingend — the parties cannot contract around it to the worker’s disadvantage even with explicit consent. Defensive drafting therefore distinguishes between what the contract can shape (place, duties, optional clauses, mobile-work policy) and what it cannot displace (NachwG catalogue, KSchG protection, BUrlG floor, § 622 escalation, § 623 Schriftform).
