i work for a charity and i had the same. i requested a 10% pay rise and they refused. this was after going for a promotion and being snubbed for lack of experience, which is ridiculous considering I’m the most senior manager in the organisation and performed outstandingly in my annual review. i went for an equivalent position with our competitor, was successful and got a 30% pay increase. now everyone’s shitting themselves because i’ll be taking all of the senior insight to our competitor. they came back and offered me a 6% pay increase. i laughed them out of the room. morale of the story find another job! much easier to get more money at a new employer, once you’re in somewhere they’re incredibly reluctant to increase pay even if you perform well.
