I gave notice to my HR Manager that I wanted to leave my job because of a new job offer. We verbally agreed on 4 weeks notice, even though my contract says that I should work a minimum of 3 months notice. The contract does, however, say 'By mutual agreement, these notice periods may be waived.' I set the wheels in motion with my new job contract and agreed on a start date on the Monday after the 4 weeks.
However, a senior manager has said to the HR Manager that they are not happy with this and wants me to work the 3 months. This is 3 days after we had agreed on the notice period. I am now being told that they can contact my new firm and let them know this. But how can they ask the new firm for a new start date without admitting to the fact that they agreed on a 4 week notice period? What options do I have to ensure that I can leave in 4 weeks time? In an ideal world I would leave today, because I hate my job and the situation that management has put me in. I am also worried that my new employer will not wait for 3 months, and I am really worried about missing this opportunity.
My plan at the moment is to send an email to the HR Manager requesting written confirmation. Although, I'm not sure the HR Manager will give this to me now she's been asked to increase my notice to 3 months.
