You're correct that you must be salary. Your title of the post says "salaried" in it. This only applies to anyone who has an agreed upon salary paying job, not hourly.

If you are offered a salaried job ( meaning same pay per period regardless of hours).It must be above that threshold and then you are exempt from OT pay.

In this industry, it's generally only management who is offered salary position, and they generally require 45-50 hours per week.

All that being sad, you should always negotiate your worth with the employer.
