Running a business while being employed?

Hello.

I was wondering whether it is allowed to run a business like I dunno selling flowers or running an online shop while being employed full-time for a certain company.

Does Swiss law allow this?

Thanks in advance for the answer.

Cheers.

Check your work contract to see if your employer allows this.

Yeah, nothing is mentioned about this in my job contract.

If the business is the same as where you are employed, then it is considered "Concurrence déloyal" under Suisse Law. you must inform your employer.
