6 weeks into a new job, with no warning, my daughter went in to work today and was told that her employment is terminated as of today due to her performance. I know she exceeded her target for January and is on target for February. Never given any prior warning. She was being harassed by a colleague and complained. I think this is the real reason but her Manager insisted it was performance. They have offered her 3weeks pay if she sign this long waiver about not taking this further etc - what can she do?
