The difference between "losing" and "loosing", and "lose" and "loose" is enormous.
Seriously, spelling aside, if you don't stick up for yourself and your rights (sure,they want you to go quietly!) then the message simply gets sent that it is ok to screw overseas workers (meaning all, not just so-called 'fat cat' expats).
You put in the time, you are entitled. The local laws, as well intentioned as they are, might not contemplate your questioning the lack of payout after years of service.
What do you have to lose (or loose)?
Good luck to you >>> we are all pulling for you
