Are we flirting with overtime violations by playing fast and loose with our job descriptions?

Q: “My company is trying to determine which of our support staff should be considered exempt; specifically, our administrative assistants and our specialists. Typically, we are requiring a college degree and 0-6 years of experience for various levels of our specialists, except for Level 1 specialists, who are nonexempt. Our problem stems from the fact that we have a good number of specialists performing ‘admin work at specialist pay.’ Do we need to re-write our job descriptions?” – Anonymous, Washington
