If, on the other hand, the manager's trust has no relevance here, because you are not setting your own time-work estimates, then have at it!
Work planning should be a team effort.
But my comment stems from someone above who said they do the minimum amount of work possible. This sucks for the team, who is working hard and trying to make progress, meanwhile this person is barely doing any work every day in between gaming or reddit or whatever, but (presumably) still joins stand-ups and Slack to chime in with whatever "complication" he's having to work through that day, and always gives the impression that their work is super tricky.
