I used to believe the common misconception that being a salaried employee means overtime laws didn't apply. Fun fact: that isn't always true. Make sure to learn your rights.
It's not just receiving a salary. You have to earn at least $684 a week AND meet the duties requirements. Administrative job with no decision-making authority? Congratulations, you don't qualify for FLSA exemption status.
IANAL, so do your own research. Your state may have stricter requirements, too. Know your rights. (Then start demanding more!)
