My job's also exempt; we get comp time or time and a half if we go over forty hours. Fortunately with the state, because there's a use-it-or-lose-it for plain comp after x amount of time has passed (though the time limit was like two or three years, so you had a while), it's unofficial policy to make sure it's used and managers and supervisors watch for that in leave balances and have called people in to get them to schedule a long weekend or something to get rid of it. And they're serious about it; when I was a caseworker, one guy took off a week every month for almost a year to burn out his before they finally instituted an option to have comp time earned in a month paid out instead of banked, and early in my time in testing, one woman took a lot of four day weekends.
