Emotions are certainly present on both sides after quitting your job. When employees leave, sometimes the boss's true colors are revealed.
Some behaviors show bosses that you don't handle an employee's termination well. If you have resigned, you no longer exist for your boss. If even a calm conversation does not improve your behavior, you can contact the works council or a union. As an employee, you also need an employment reference, so you should continue to work diligently, then it is more likely that you will receive a favorable reference more quickly. You can also recognize bad behavior if you are overwhelmed with tasks. The Arbeitsabc.de portal informs that, on the one hand, this can be the case if the boss has already finished with you. On the other hand, it is also possible that he will resent your decision. It is important to distinguish unprofessional behavior from the good of the company. “Condemning the employee or insulting him is the worst case scenario,” says Maren Ulbrich, consultant for craft companies.
