sack her and don't look back 4 weeks notice and be done with it take it from someone with experience she will just carry on taking the biscuit, i did the whole "sit down and talk" it doesn't make a difference. if you really want a turn around re-write the contract and remove the sick pay going forward and then see what happens however mine had no sick pay and still had 9 days off in 3 n hlf months. not worth it get rid!
