If you are dismissed or your temporary contract is not extended at your employer’s request, you are entitled to a transition payment. This option is available to you even if you decide to leave on your own accord because of your employer’s very negligent actions.
Starting from January 2021, you are eligible for a transition allowance if you are fired before the end of your employment contract. This is how the transition compensation is determined:
For every year worked, you will receive an allowance equal to 1/3 of your normal salary per full year worked. For example, if your monthly salary is 3000 euros and you have worked for a total of years, then you will receive an allowance of 2 * (3000*1/3) = 2000 euros.
