I'm in a fairly senior role but one which is easy to fill. Am awaiting my contract for a new, better job and have just checked my contract to see what my notice period is. Because I have been here longer than two years, it has increased from one to three months. I stupidly didn't read this part when I joined and have told new company my notice period is one month. I have a team that can take on my work, there is nothing strategically significant happening during this time that I'd need to manage. Has anyone in a similar position managed to negotiate it down, and if so, any tips??
