From an employers point of view, tracking hours does not make sense. At least as long as we are talking about creative work, where people tend to stay longer than they would be required to, without even noticing how much time they were working.

At least in Germany, working unions are fighting against not counting working hours, because it is better for the employees and is also a saftey net against related health issues. Without counting, legal rules are not enforceable and people may even work on weekends without any compensation. This also leads to the fact that managers start to expect those extra hours from everyone, and consequently see it as an lack of motivation or dedication not doing them.
