sristakdas is certainly CORRECT.. the company can NEVER EVER SUE YOUR WIFE.... hiring somebody on family visa without WORK PERMIT is illegal..this will cause penalty for the company..we have family visas working with us (husband visa) and I applied work permit for them because of the fear of its circumstances...

If ever your wife has work permit, SHE CAN STILL RESIGN by giving the company 1month notice...DON'T WORRY your company's wife will never win this game...

NO COMPANY CAN RESIST RESIGNATION OF THEIR STAFF..BUT IT IS THE OBLIGATION OF THE STAFF to give the company 1-3 months notice...
