I may be overthinking this, but I would like some input. The senior person on my team has a habit of taking time off (being sick, or his kid is sick) pretty much as soon as he has 8 hours of PTO or Sick Time. I try to be a results focussed manager, and not effort focussed, and to this end he does get his job done. And I'm not saying his reasons aren't legitimate, but there is a pattern there, and I'm wondering if I should be concerned or say something.
In addition, he has a habit of coming in later than others on the team and leaving either earlier or at the same time. I know, from emails and work being done, that he is putting in a lot of time at nights doing his work, but not everyone knows that and there's a perception growing that he isn't putting in his time. I do plan on speaking to him about this, explaining the perception and his responsibilities as the senior person on the team, but I'd appreciate any advice.
