Part-time work (TzBfG) explained simply

Definition

Part-time work means working fewer hours on a regular basis than a comparable full-time employee. In companies with more than 15 employees, staff are entitled to reduce their working hours after six months’ service – provided there are no compelling operational reasons to the contrary. The request must be made in writing at least three months before the desired start date; if the employer does not respond in time, the request is deemed to have been approved. In addition, there is ‘bridging part-time work’: in companies with 45 or more employees, staff can reduce their hours for one to five years and then automatically return to their previous working hours. Part-time employees must not be treated less favourably than full-time staff because of their reduced hours.

Classification under employment law

Employees in companies with more than 15 staff members are entitled to a reduction in working hours after six months’ service (Section 8 of the German Part-Time and Fixed-Term Employment Act), provided there are no pressing operational reasons to the contrary. Since 2019, there has also been an entitlement to bridging part-time work with a right to return.


Distinction from related terms

Bridge part-time work: Bridge part-time work is a fixed-term part-time arrangement with a statutory right to return to the original working hours. ‘Normal’ part-time work under the TzBfG is generally of indefinite duration.

Marginal employment (mini-job): A mini-job is defined by an earnings threshold. Part-time work, by contrast, merely describes a reduced working time, regardless of remuneration.

Practical tip

Submit your request to work part-time in writing and in good time – at least three months before your desired start date. If your employer does not respond within the specified time limit, your request is deemed to have been approved. This is a frequently overlooked but highly effective mechanism. 

Yes, provided certain conditions are met, such as a minimum length of employment and a sufficient size of the business.

Yes, but only for operational reasons. These must be clear and specific.

As a rule, the application must be submitted no later than three months before the desired start date.

Only in certain cases, such as in the case of bridging part-time work. A general right to return does not always apply.
