IKA And other taxes

Hello! I am new in Greece as domestic helper. But i am not working with the employer who signed my contract. My lawyer told me that my IKa and other taxes should be paid under my contract employer for atleast 1 year before i could work to hotel or restaurant. Is it possible that i will be the one paying may taxes under my employer's name even if i'm working in hotel, he is willing to do so because he only signed my papers to come to greece and find another work.
