She admitted yesterday she'd been staying past her contracted times, 10-15 mins here and there deliberately and has managed to accrue a whole week of TOIL!? we are a very small team who has an issue (imo) with sickness. Although we all have different roles, it inevitably impacts everyone when someone is off, even for leave. She also arranges appointments and runs regular "errands" on her working days (so leaves the workplace for up to an hour) when she has every Monday and Tuesday off. She is incredibly skillful at "looking busy" and talking constantly about having loads to do. Yes, I do notice it because none of us imo are busy enough to accrue TOIL.
She said she has leave left but wanted to 'save' it. I'm feeling pissed off. She has no reason to stay late every day as she does, genuinely, it's not that kind of role. I'm thinking of speaking to the manager about what she said regarding the TOIL. AIBU or should I keep my nose out?
