In this matter too, you must comply with the control regulations of your employer. It is therefore advisable to participate in a meeting with your employer. If the company doctor has clearly advised (and recorded) that it is better for your recovery not to have contact with your employer, then this is not necessary.
If this advice is not available, you run the risk that it will affect your salary, or perhaps your future at the company. Know that you can also bring someone from your family or circle of friends to the interview if you feel more comfortable with it. If necessary, request a telephone conversation with your employer first and help you find solutions.
