Abolish the overtime exemption for computer systems analysts, computer programmers, and software engineers. Make it unprofitable to extract labor until someone dies. All other actions are impotent.
Not to mention that even if timesheets were used, they provide no guarantees. We always had to get management permission to put overtime in, but no one really knew how much time we worked - especially with a possibility of remote work.
This can only be fixed by pervasive monitoring, and IMHO this leads to a very unpleasant workspace.
Option 1: you do as told and leave home at 5pm. You spend 40 hours per week exactly, but work is not getting done, so people are complaining about your performance. Your manager is putting more pressure on you, you are worried about getting fired.
Option 2: you record 40 hours per week, but actually work for 80. Sure your home life suffers but at least the manager is off your back. You are getting compliments about performance and vague promises about raise sometimes in the future maybe.
Which option do you think people will choose?
Give people who want it a legal foundation for getting paid for the work they do and people who find themselves in the situation you describe can chart their own path out.
If you want to fudge numbers and be complicit in your own exploitation, you do you. But please, don't undermine everyone else's legal infrastructure to get paid for the work they do.
Which would you choose? Based on "be complicit in your own exploitation", I am guessing you'd choose option 1, work exactly 40 hours, don't get things done on time, and make your boss unhappy? Well, good news: you can do this today, even if you are exempt, no need to ask for a law.
(I suspect you are hoping for option 3, "get my boss to approve overtime so I can work extra hours, get all the stuff done, and get extra $$$". This won't happen. If the boss is evil, they really see no upside in this so they won't approve the overtime. If the boss is nice, they won't give you too many tasks to begin with.)
