It is always difficult to get a dismissal. In some cases, however, a dismissal is not valid, e.g. if it was made during illness, pregnancy or military service. If the notice was given before the illness, it is valid, but the notice period is extended – and not only by the number of sick days. Furthermore, a dismissal can also be considered as abusive, which leads to a compensation payment by the employer.
Let your dismissal legally reviewed and get advice how you should proceed. At a fixed price.
