As employees realize they’re getting a bad deal and that they can find a better ratio of pay to hours worked at other companies, they leave.
If I'm an employee with miniscule equity, why would I put in any more time and effort than what was agreed?
If so, then yes you should only work those hours.
However, if you’re a typical full-time employee in most countries you don’t have agreed upon hours.

Again, if something was agreed upon you should follow that. In most full-time jobs they’re not going to specify a maximum number of working hours. It’s your job to explain what can be done in a workweek and push back when something can’t be done. If it persists and you don’t like it then you find another job. Vote with your feet.
