Luxembourg (LU)
Luxembourg is a tiny but remarkably prosperous constitutional monarchy at the heart of Europe — a founding member of both the EU and NATO — celebrated as the world's most productive economy per capita, the EU's premier financial centre, and home to the highest minimum wage on the continent.
Employment Rights
Sick leave, dismissal protection and red flags in Luxembourg.
Luxembourg has strong employee protections under the Code du Travail (Labour Code). Employees benefit from: the EU's highest minimum wage, generous leave entitlements, strong anti-dismissal protections, and an effective labour inspection system (Inspection du Travail et des Mines — ITM). The tripartite system (government, employers, unions) is central to Luxembourg's social model. The main unions are OGBL (independent) and LCGB (Christian). The legal system is French in structure, with labour disputes resolved through the Tribunal du Travail (Labour Tribunal). Non-residents working in Luxembourg (frontaliers — approximately 200,000/day from France, Belgium, Germany) have the same employment rights as residents under Luxembourg labour law but different tax and social security rules.
Sick leave
Rules: On the first day of illness, the employee must notify the employer no later than the normal start of working time. Within 3 days of falling ill, a médecin-certificat (medical certificate from a doctor) must be sent to both the employer AND the CNS. Failure to provide the certificate on time can result in loss of salary for the uncertified period.
Doctor note: Within 3 days of illness starting (day 1 is day of illness onset)
Employer pay: For the first 77 days of illness in a rolling 12-month period: employer pays full salary (through Mutualité des Employeurs system). From day 78 onwards: CNS pays sick benefit (approximately 100% of salary up to a ceiling). Long-term illness (beyond 26 weeks): special CNS invalidity procedures apply.
Long-term: If ill for more than 78 days continuously: CNS takes over payment (indemnités pécuniaires de maladie — approximately 100% of salary up to CNS ceiling). After 52 weeks of illness, pension invalidity assessment begins. Very generous system — virtually no risk of financial hardship from extended illness for Luxembourg employees.
Dismissal protection
Law: Code du Travail (Labour Code) provides strong protection against arbitrary dismissal. Dismissal must be justified by real and serious causes (motif légitime): either relating to the employee's conduct, their professional capability, or economic redundancy (licenciement économique). The employer must state the reasons in writing. Wrongful dismissal (licenciement abusif) gives the right to damages of typically 1–2 months salary per year of service (at the tribunal's discretion), or reinstatement.
Deadline to sue: 3 months from the date of dismissal to file a challenge (contestation du licenciement) with the Tribunal du Travail. Missing this deadline forfeits the right to challenge.
Probation
Période d'essai (probationary period) must be explicitly written in the employment contract. Duration: minimum 2 weeks, maximum 6 months for white-collar workers (employés privés). During probation: notice is very short — 1 day during the first 2 weeks, then 1 day per fortnight of probation completed. After probation, full Labour Code dismissal protections apply. Cannot be renewed — once probation ends (or if no probation was written in the contract), full protections apply immediately.
Notice periods
Statutory notice (délai de congé) for employer-initiated dismissal: less than 5 years service = 2 months; 5–10 years = 4 months; 10+ years = 6 months. Payment in lieu of notice is permitted. No notice during probation (subject to short notice rules). Immediate dismissal with cause (faute grave) is permitted for serious misconduct but must be initiated within 8 days of the employer learning of the misconduct.
Working time
Max hours: 40 hours per week standard. Legal maximum: 48 hours per week (including overtime) in any 12-week period. Daily maximum: 10 hours. Collective agreements may set shorter hours for certain sectors.
Min rest: 11 consecutive hours daily rest between working periods. 45 minutes break if working more than 6 hours. Weekly rest: at least 44 consecutive hours including Sunday in principle.
Overtime: Work beyond 40 hours/week is overtime. Compensation: either 40% premium (surpay) on overtime hours, or compensatory time off (récupération). Maximum 2 hours of overtime per day. Night work and Sunday work attract additional premiums specified by collective agreement.
Vacation
Minimum 26 days paid annual leave per year (congé annuel légal) for a 5-day work week. Luxembourg law provides 26 days minimum — significantly more than the EU directive minimum of 20 days. Most collective agreements provide 28–32 days. Public holidays: 11 per year (National Day on 23 June, Europe Day on 9 May, and others). Holidays not taken within the year must generally be carried over to a limited period — check your collective agreement. Pay during leave is full normal salary.
Anti-discrimination
Luxembourg's labour law prohibits discrimination on grounds of race, ethnicity, gender, sexual orientation, age, religion, disability, and national origin, in compliance with EU Equal Treatment Directives. The Centre pour l'égalité de traitement (CCDH) handles complaints. As a highly international workforce, direct nationality discrimination is rare but can occur — particularly for Luxembourgish-language requirements in non-language roles. EU citizens have equal employment rights to Luxembourg nationals for private sector roles. Public sector roles (fonctionnaire — civil servant) are restricted to Luxembourg nationals for some positions, but many public sector positions are open to EU citizens.
Contract red flags
- !No written contract (contrat de travail) — all employment in Luxembourg must be in writing
- !Trial period (période d'essai) stated as more than 6 months — illegal
- !Waiving rights to overtime pay or leave — waiver of statutory rights is void
- !No mention of collective agreement (convention collective) when one applies to your sector
- !Clause requiring reimbursement of training costs lasting longer than 3 years or exceeding legal limits
- !Non-compete clause (clause de non-concurrence) without proper compensation — must meet Code du Travail requirements to be valid
- !Contract in a language you do not understand — while legally valid if signed, you have a right to understand what you sign
- !CDD (fixed-term contract) without stating the reason for the fixed term (required by law)
- !Working hours stated as variable without the legal framework for variable schedules
- !Net salary stated instead of gross salary — always verify the gross and understand the deductions
- !Salary below the Salaire Social Minimum (SSM) — €2,703.74/month gross for non-qualified workers; €3,244.48/month for qualified workers from May 2025 (indexation applies; verify at ITM when next adjustment occurs in Q3 2026). Luxembourg has the EU's highest statutory minimum wage.
