Manager: We (meaning you) need to do task A. How long will it take?
Me: Task A will take X days to do.
Manager: That seems awful long.
Me: How long do you think it should take?
Manager: It surely could not take any longer than Y days.
Me: Ok, it seems you have an answer to your question then.
Later:
Manager: It’s been Y days, why isn’t task A done yet?
Made me want to become that notorious software architect, just to be the reason that “X is going to take Y days. Want faster? Change your fucking expectations/scope of X”
It’s nice having that kind of pull/weight to throw around, but sometimes the boss still won’t listen. Different industry, we had a major change in tax law happen. I read about it, figured out how to do it, then told the boss that we needed to start now training the company on the new method because it would take a year for us to catch up.
His response was to ignore it, because “congress is going to undo the law”. I left for another firm, precisely because I didn’t want to be in charge of the last minute project he’d assign with a month to go on a hard legal deadline. Got a phone call about two weeks before the deadline. Fortunately it went to voicemail because I couldn’t stop laughing for like half an hour.
