If you would like to employ your own staff, you will need to observe a number of rights and obligations. In order to hire staff in the first place, you will need a company number. To find out how to get a company number and what else to bear in mind, please refer to the Startup Portal (German). Remember that as an employer, you will need to pay tax and social insurance contributions.
You will need to observe a number of legal regulations as you deal with your employees, too. For example, you will need to continue paying salaries and wages even if your staff is ill, and your employees have a right to annual leave. It’s important to note that you can’t fire employees without a valid reason, either. You should make sure to find out your rights and obligations vis-à-vis your staff. The information provided by the Business Portal will point you in the right direction.
