I was offered a new position/promotion a few months ago (informally) by my boss and just found out through the grapevine, not even first hand, that actually they have hired someone new to do the position as they want to keep me as a minion.
Based on the offer of the promotion I stated I would increase my working days from 2-4, however after the disappointment of being the last to find out this would not be happening, I decided not to increase my days as it would be stressful to work extra when I have small children and without the promotion, not really worth my while. I informed my boss by email that based on the situation changing I had charged my mind about increasing my working days and received a veiled threat back that if I didn’t increase my days as I said it would cause a huge problem for the office and I would have problems progressing with any promotions in the future.
What should I say/do?
