Thank god for labor law
Which is the main reason those of us at the coal face get paid overtime and hence only do so intermittently. Those they can make exempt that aren't senior managers are made exempt so they can work you more hours than they pay you for. In most cases as many as they can get away with.
They act like making you exempt is some big win for you as the employee, more likely it's a suckers game till they claw their way up high enough to look busier than they are.
