There is nothing more annoying than someone at work remarking on your comings and goings. Why does it matter to you that I just got to work? I don’t report to you and we don’t even work on the same team! For you information, I’m suffering from severe allergies and not only do I get to work late I still get more done that my team.
You on the other hand, since we started together had been late on our first day, had a terrible attitude and are wholly unsuitable for the role you’re in - mind your business!
