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?
One time we spent like more than an hour in a horrible meeting to plan out how long the next step of a project would take. 4 weeks, we said. Management came back and said to do it in 2. Well, why did we fucking have the meeting if they had a deadline in mind already?
On the other hand, at my current job I have seen a lot of “oh that’s going to take a couple days” protests for things that are 20 minutes of work.
Seems like the solution is to get rid of out of touch management.
