Software development operates largely on trust that everyone on the team is putting in real effort. The manager trusts that when it takes you a week to finish a task, it's because it actually took a week of work, not a few minutes on Monday and then you watched YouTube vids and were on your XBox the rest of the week. And not just the manager -- everyone at the company would almost certainly like to move faster, and wouldn't be happy to know that features and bugfixes could be landing 5x faster, except for people who figured out that no one's checking up on them.
