Uhhhh this is exactly how you are supposed to work? I learned that early on. Your boss isn't sitting there watching your every move. You could save the company a trillion dollars and no one would give a fuck if you never tell anyone.
No one is getting a raise or promoted cause they worked 60 hours a week. Working on high visibility projects that are easy is the secret. And if you can't get added to a high visibility project, make your projects high visibility.
Fix the work culture if you don't like it Price. Otherwise go fuck yourself.
