Personal working time adjustment

Take advantage of flexible working hours to gain training
Last update : 20.06.2023

General information

Thanks to flexitime, which allows for flexible working time management, the employee can ask for his or her working hours and daily working time to be adjusted, taking into account his or her personal convenience.

Working time should be adjusted in compliance with:

  • the requirements of the department and the justified wishes of other employees,
  • the legal limits for working time. Apart from legal exceptions, working time cannot exceed 10 hours per day or 48 hours per week,
  • pre-defined rules in the context of flexitime regulations.


There is no universal system for flexitime management, but only recommendations for the parties involved in managing regulations for flexible working hours.

Flexitime regulations may mean that:

  • the management of working hour deficits noted at the end of the reference period may be subject to specific solutions. In this case, the maximum deficit amount for each reference period can be increased for the employee undertaking training, and similarly the deadline for clearing the deficits can be extended,
  • core time during which employees must be at work can be adjusted on an individual basis, according to the specific constraints of those undertaking training,
  • the total range (start and end of working hours) including core and flexible time can be extended beyond the normal limits.

Refusal by the employer

As far as companies are concerned, it may be stipulated that those who:

  • either refuse to introduce a flexible adjustment of working time for learners,
  • or refuse to adjust hours in the way intended by this measure,

provide reasons for their refusal in terms of departmental needs or requirements for the efficient organisation of the company.

An internal corporate body may be set up in agreement with staff representatives in order to settle any disagreements relating to the assessment of the grounds cited in respect of flexitime.

Limits of the system

Departmental needs and requirements for the efficient organisation of the company may be used to oppose the employee's or staff representatives' request. It is therefore not an absolute right, but merely a possibility.
