The Continued Remuneration Act (EntFG) regulates whether your employer must continue to pay your salary if you report sick. According to § 3, you as an employee are entitled to have your employer continue to pay you your full salary for up to six weeks if you are unable to work through no fault of your own.
If you are unable to work through no fault of your own, you are also entitled to continued payment of your salary. This means that if you are ill or unable to work, your employer must continue to pay your salary for up to six weeks.
