Work Organisation Plan (POT) in Luxembourg

Axis 1 — Establishment conditions

Deadline: 5 clear days before the period starts

The employer must establish the POT no later than five clear days before the start of the reference period. Where the reference period is one month or longer, the POT must cover at least one month (Art. L.211-7).

Mandatory content — required on pain of invalidity

The POT is only valid if it contains all of the following items:

Axis 2 — Consultation procedure

Mandatory prior opinion: 5 days before entry into force

Every POT must be submitted for an opinion to the staff delegation or, where there is no delegation, to the employees concerned directly, no later than five days before its entry into force (Art. L.211-7).

In case of disagreement: ITM → ONC procedure

If the delegation issues a reasoned negative opinion, the following procedure is triggered:

1. Referral to the Director of the ITM (Labour and Mines Inspectorate), who has one month to seek an agreement between the parties.
2. If unsuccessful, referral to the National Conciliation Office (ONC).

Axis 3 — Modifications during the period

The employer may modify the POT during its application. The effect on the classification of hours worked depends entirely on the notice period given.

Notice ≥ 3 days: no overtime

If the modification is notified with at least 3 days' notice, work carried out within the limits of the modified POT is not classified as overtime, even if it exceeds the original schedule. The employer retains full organisational flexibility (Art. L.211-7).

Notice < 3 days: enhanced compensation regime

For a modification given with less than 3 days' notice, without any increase in the total volume of hours, a progressive compensation mechanism applies:

• Hours exceeding the original schedule by 2 hours or less: compensated at 1 hour for 1 hour (standard rate).
• Hours exceeding the original schedule by more than 2 hours: compensated at 1.2 hours for every hour worked (Art. L.211-7).

Employee's right to refuse

Where notice is less than 3 days, the employee may refuse the schedule change on compelling and well-founded grounds. This right to refuse is only overridden in cases of force majeure (Art. L.211-7). Whether grounds are "compelling and well-founded" is ultimately assessed by a court in the event of a dispute.

Axis 4 — Special cases

HORECA: mandatory prerequisite for sector-specific reference periods

For hotel and restaurant businesses with more than 15 employees, establishing a POT is an indispensable prerequisite for applying the sector-specific reference periods provided for under the HORECA collective agreement (Art. L.212-6). Without a properly completed POT, the employer cannot rely on those arrangements.

Part-time employees

The POT must precisely set out the rules applicable to part-time employees, particularly the limits on exceeding their contractual working hours. These limits determine the classification of supplementary hours (Art. L.123-1).

Young workers: dedicated chapter mandatory

Where the business employs young workers (15–18), the POT must include a dedicated chapter on their working arrangements, covering the specific caps and prohibitions applicable to them (Art. L.344-6).

Axis 5 — Alternative: flexible working hours

A flexible working hours regulation may replace the POT system (Art. L.211-8). Flexible working allows employees to arrange their own hours within the service requirements and statutory limits:

• Maximum daily duration: 10 hours;
• Maximum weekly duration: 48 hours.
