I was "offered" a salary role with a promotion once, and I asked them if it was exempt or nonexempt. They acted confused, then said exempt. I was denied the promotion, and took a job elsewhere. Fuck that nonsense.
This is the threshold they use as the cutoff for overtime pay. Originally the cutoff was $35,000 a year and then you wouldn't have to pay any overtime if the salary is over that. This would require overtime pay for any salaried employees that are under $55,000 a year. It's a good thing and it's being used to come back practices that major retailers like Dollar general embrace.
2x minimum wage for a 40 hour work week is the salary threshold. If you make less your employer is breaking the law. In California the salary threshold is currently $64,480.
Imagine being told that you have to work for free because they deem you worked too many hours in a world where you can hardly make enough to pay for rent let alone buy a house.
