I hate jira because it slots your work stupidly by the management, or so I feel it.

A manager usually works with time slots, say 8 a day (or whatever), they are all mostly disconnected, like do meeting with A, go to standup of team B, PMD for dev C etc etc. Dev isn't like that but everyone seems to start thinking it is: how many "items" was finalised last "sprint" etc and other stupid metrics.

Am I alone here or is there even worse things with jira in your opinions?
