Gleichbehandlungsgrundsatz (equal treatment principle)
What the German equal treatment principle requires, how it differs from the AGG and which deadlines apply where someone is disadvantaged.
1. What is Gleichbehandlungsgrundsatz (equal treatment principle)?
German employment law contains two different equal treatment requirements which are constantly run together in practice. In English both easily collapse into "equal treatment"; they are not the same thing.
The employment law equal treatment principle is not codified but developed by the courts. It prohibits excluding individual employees from a general arrangement without an objective reason. It therefore bites where the employer acts on a principle it has set itself – on a bonus paid to everyone, for instance. It does not cover individual agreements: negotiating higher pay for yourself wrongs nobody.
The General Equal Treatment Act (AGG) pursues a different aim. Under Section 7 AGG it prohibits disadvantage on grounds of the eight characteristics exhaustively listed in Section 1 AGG: race or ethnic origin, sex, religion or belief, disability, age and sexual identity. It applies regardless of whether any collective arrangement exists – and it bites from the recruitment process onwards.
2. Origin and development
The employment law equal treatment principle grew from a simple insight: where an employer sets a rule for many, it binds itself. It may not then arbitrarily take individuals out, because its distributive decision operates like a norm. The principle is thus a limit on freedom of contract that bites only where the employer acts collectively.
The AGG has a different origin: it implements European anti-discrimination directives. Its approach is not self-binding but the protection of particular, historically disadvantaged characteristics – and that is why the list in Section 1 AGG is exhaustive. Someone who feels disadvantaged but is not affected in one of those characteristics cannot rely on the AGG.
What matters in practice is the burden of proof rule: anyone setting out indications suggesting disadvantage on a protected ground shifts the burden – the employer must then show that there was no breach. That reversal is what makes the Act effective in practice, and it is why documenting selection decisions matters so much.
3. Core principles and how it works
The equal treatment principle applies only to collective action
It prohibits taking individuals out of a general arrangement without an objective reason. Individually negotiated terms are not covered.
Eight characteristics, exhaustively
Section 1 AGG names them. Other grounds of distinction – length of service, performance, location – do not fall under it, so long as they do not indirectly bear on a protected characteristic.
Direct and indirect disadvantage
Direct is open unequal treatment. Indirect is a neutral rule that in fact particularly affects people with a characteristic – a rule disadvantaging part-time staff and thereby predominantly women, for instance.
Justification is possible but narrow
The AGG permits different treatment where a characteristic is a genuine occupational requirement or an objective reason exists. For age the scope for justification is widest.
An easier burden for those affected
Anyone putting forward indications suggesting disadvantage shifts the burden of proof to the employer. An unclear or undocumented selection decision thereby becomes a risk.
A short deadline for bringing a claim
Claims under Section 15 AGG must be asserted in writing within a short period. It runs independently of any unfair dismissal claim.
Compensation without a right to the job
A disadvantaged applicant can claim compensation without having any entitlement to the position. Section 15 AGG separates the two expressly.
4. Who is Gleichbehandlungsgrundsatz (equal treatment principle) relevant for?
- Every employer – the AGG applies with no size threshold and from the recruitment process onwards. - Recruiting and selection – most AGG cases arise there, often already in the job advertisement. - Managers – appraisals, promotions and the allocation of work are covered. - Works councils – they take part in enforcement and have rights of their own in cases of serious breach. - Those responsible for pay – pay systems can disadvantage indirectly, entirely without intent.
5. How it differs from related terms
- Equal treatment principle and AGG – one requires consistency with self-imposed rules, the other protects particular characteristics. A breach of one is not a breach of the other. - AGG and Article 3 of the Basic Law – the Basic Law binds the state directly; between private parties it operates only indirectly. The AGG makes the evaluation directly applicable to the employment relationship. - AGG and equal pay – the right to equal pay for the same or equivalent work is governed separately and carries its own rights to information. - AGG and the prohibition on disadvantaging part-timers – the TzBfG prohibits less favourable treatment because of part-time or fixed-term status; that is a separate ground alongside the AGG. - Disadvantage and victimisation – penalising someone for lawfully exercising a right is separately prohibited and needs no protected characteristic.
6. Variants and adaptations
The most frequent categories of case in practice:
- The job advertisement – wording that is not gender-neutral, or refers to age, is a classic indication and frequently establishes the reversal of the burden on its own. - The selection decision – where the grounds for rejection are not documented, discharging the burden is difficult. - Pay systems – criteria tied to length of service or full-time status can disadvantage indirectly. - Promotion and appraisal – a lack of traceability tells particularly here. - Harassment – it too is a disadvantage within the meaning of the AGG; the employer has duties of protection and organisation. - Dismissal – dismissal protection rules apply; the AGG evaluations feed into them.
7. Advantages and challenges
Advantages
- Creates traceable standards for selection, pay and promotion
- The easier burden of proof makes the prohibition enforceable in practice
- Documented procedures improve the quality of decisions regardless of legal risk
- The equal treatment principle prevents arbitrary exceptions to bonus arrangements
- Clear rules relieve managers in difficult distributive decisions
Challenges
- Confusing the two principles produces false expectations on both sides
- The reversal of the burden hits employers who decide carefully but without documentation
- Indirect disadvantage arises without intent and is recognised late
- The short deadline for claiming regularly surprises those affected
- The scope for justification is narrow and hard to assess in the individual case
- Formulaic compliance without lived practice offers no protection
8. Best practices for implementation
Document selection decisions
The requirement profile, the assessment criteria, the grounds for rejection. That is the only effective way of discharging the burden once it shifts – and it cannot be produced afterwards.
Have job advertisements reviewed
Gender-neutral wording, no reference to age, no requirements aimed without objective reason at a protected characteristic. A single word can trigger the reversal of the burden – which is worth checking on any advertisement drafted centrally and then translated.
Keep application documents for a limited time
Long enough for the claim period, no longer. That is also a data protection requirement.
Distribute bonuses on a recognisable principle
Paying under a general rule means having to hold to it. Exceptions need an objective reason that can be stated.
Set up a complaints body and make it known
The AGG requires a body those affected can turn to. It only works where it is known and reachable.
9. Tips for employers and employees
For employers
- **Document the selection** – the burden can shift, and then only what is written counts
- **Word advertisements neutrally** – one word suffices as an indication
- **Think about indirect disadvantage** – neutral rules can hit particular groups
- **Set up a complaints body** – the AGG requires one expressly
For employees
- **Watch the short deadline** – claims under Section 15 AGG must be asserted promptly and in writing
- **Indications suffice at first** – you do not have to prove the disadvantage, only make it appear likely
- **Compensation without a right to the job** – the AGG separates the two
- **Not every unequal treatment is prohibited** – the AGG protects eight characteristics, no others
10. Conclusion
Two principles that belong kept apart. The employment law equal treatment principle requires consistency: acting under a general rule means not taking individuals out of it without an objective reason. It does not apply to individually negotiated terms.
The AGG, by contrast, protects eight exhaustively named characteristics – regardless of any collective arrangement, and from the recruitment process onwards. Someone who feels unfairly treated without one of those characteristics being affected cannot rely on it.
What decides matters in practice is the easier burden of proof: putting forward indications suggesting disadvantage shifts the burden to the employer. The risk therefore moves from the decision to its traceability – a careful but undocumented selection is practically indefensible in proceedings.
For an international group that has one concrete consequence. A job advertisement written centrally and translated into German carries wording conventions from another market, and a single word – on age, on gender, on an unnecessary requirement – is enough to shift the burden before anyone has read an application.
