I have been working at a software development company as a full-time developer here in the UK for the past 16 years. Recently I was told that those of us with one month notice periods stipulated in our contracts would have them changed to a "standard" three month notice period.
Whilst I understand why this is advantageous for the employer, it feels as though they are taking something from me (my availability to potential future employers, should I choose to leave), and thus I'm losing-out somehow.
I've read other questions on this site concerning employers extending notice periods, such as: Refusing increase of the notice period politely, and was wondering whether any software development managers reading this would think it rude, daft, or otherwise unprofessional to ask for a one-off payment of two months wages for the two months additional notice that I am being asked to accept?
I don't think my employer will be open to leaving the notice period as is, or negotiating a period of a different length, as there are other employees with three month notice periods, and I think they are trying to standardise on this internally.
I am aware that my employers could, of course, choose to end my contract if I refuse to accept the new terms.
