My question involves labor and employment law for the state of: California
I am working as a permanent employee , full time at a company. I plan to resign and join another company.
I may end up joining my new company while I have still not yet resigned from the old company. This overlapping situation will be only for 2-3 days at most.
Is it illegal to be with two companies , full time at the same time?
I will be getting paid by both companies during this time.
I checked I-9 form and it does not say anything anywhere about being working only full time only for one company.
