Hi, I'm really confused. I've been successful in securing a band 3 to band 4 role within the NHS. I gave my notice of 4 weeks or a touch longer to make sure in good faith my line manager had enough notice, which runs to the 21st of April but I'm away from the 23rd of April until 11th of May. My new line manager set my start date as the 12th of May to avoid 1 working day pre holiday but my current like manager refuses to change the leaving date. It currently means I will have to leave the NHS and lose my 5 year service and not get paid for my holiday. I raised to local union rep but he said I can't do anything. Surely this can't be right?!
