There are specific requirements for being exempt from overtime, even for salaried employees. There are three big exemptions, and each one has multiple requirements; You need to meet ALL of the requirements for any exemption in order to be legally exempt. I’d advise you to check the requirements here, because employers regularly misclassify workers and lie through their teeth about it to avoid paying OT. Intentional misclassification is one of the most overt ways that employers steal wages, but also extremely common in many industries.
Also, there’s a blue-collar clause that says all manual labor positions are non-exempt. So if they’re dumb enough to write manual labor into your job description, you’re non-exempt no matter how highly paid you are.
I have a coworker like that with our office phones. Our phone system rolls over to ringing the entire office if the original person doesn’t pick up. Phone lines will be dead silent all day long. Then this one coworker goes for a quick 15 minute walk, and instantly gets six phone calls back-to-back, which inevitably rings the rest of the office for each call. Then as soon as the last call wraps up, she casually strolls back in from her walk.
