If a guy always ask your whereabouts , is it a sign?

If at work every time you miss a day or schedule changes, a coworker asks a friend of yours where you are, why you're not there, could it be a sign he likes you? Once I told him my boss didn't put me on much & he joked that he didn't like that so he needs to confront him.
