I head up a team and on one of our deliverables, we're really good at. Our target is 30 and we're currently ahead of schedule. My manager isn't happy, however, and has made me feel shit for potentially delivering above target and has demanded we stick to target. It will cost us financially no more in delivery as this work is funded by an external partner. I also feel that reasons arent clear despite me asking for clarification. Is there any reason that my manager should be feeling this way?
