A social selection must always be carried out if the employer wishes to dismiss one or more employees for operational reasons and these fall under the Dismissal Protection Act (KSchG), e.g. in the case of so-called mass dismissals.
This is often neglected in practice. Therefore, if you are affected by a dismissal for operational reasons, always check whether you are "the right person" and whether an appropriate social selection has been carried out. If you have any doubts, we strongly recommend that you seek employment law expertise.
