Have you already given notice then?
It is absolutely fine to ask to negotiate your notice period down. Just ask if they would consider it as there is someone ready to step in, to allow you to take on another position. They can only say no. They may stipulate it is dependant on certain tasks being completed within the 2 months
Also just today we’ve been told that the owner (who is very seldom here - it’s a private estate) wants to speak to us about our leaving.
The truth is that there is nepotism and mismanagement (cldnt organise a p*** up in a brewery) but I don’t believe it’s in our interests to tell the truth. Was thinking of keeping it simple n gloss over real reason).
3 months seems an awful long time for a notice period.
If the company is run as you say why would you want to go back.
I've seen this management style before and it usually ends in the business going bankrupt.
