Domestic work

I am new here in Switzerland, and i don't know exactly my status as a domestic worker... I am working with a family, I have a 1 year contract but i don't have a copy of the contract... how do I know the number of hours should I work? Do I work on public holidays? on saturdays?  or how many hours a week should i work?  because I am working from sunrise to sundown and even walk the dog at 10 pm before i sleep.... everyday..

Can someone give me some info..pls?   thanks

Did you read the contract at all or did you just sign it? Have you asked for a copy?
