Your case is exactly like mine. Now, 我工人almost finish 2nd contract. I asked her if she will renew. She told me that she need to "think", I assume she唔續約and went to get a new helper, two days ago 又話做. My worry is that 請過個新既又未必好d, but 2nd contract she already become a bit lazy and start talking on the phone, don't know if I should 同佢續 :-( :-( :-(
