I’d like to be able to try to resolve what we have with the current manager.
And that’s the key to all this. How badly do you want to stick with the current company? To the extent that you’d put up with an unfair contract? Personally, I would be looking around at the same time as gicing them the option to shange the terms of the contract back in your favour.
A contract is an agreement between two parties – its terms have to suit both of them and can’t be sacrosanct just because “this is our standard contract”. Cave in on this and you are inviting the SM to believe they will always get what they want, regardless of your opinion.
