I'm in sort of the same situation. Due to covid there isn't the same amount of work for me. So I inflate my timesheets as much as possible. I'm lucky to have a few low-priority internal projects where nobody has bothered to do estimates and where there isn't a client to get mad about the bills. I'm logging a lot of bullshit hours on those.

I hate this. I'm afraid that I'll get caught and that someone will notice the tremendously low output of all the hours I log. All I want to do is having a reasonable amount of sensible work to fill my day with and knowing that I've done what is expected of me.
