to be annoyed with my colleague

[user287871297]

My colleague was off sick last Monday and Tuesday after a procedure. On Wednesday she was due back into work but told the manager she had an appointment with her consultant so needed the day off.
Today she told everyone she didn't have an appointment and she had lied because she wanted another day off to recover. I don't understand why she couldn't tell the truth.
As someone who has regular appointments with consultants which I book time off work for, AIBU to be annoyed that my colleague lied about her appointment.
Now I feel that my manager and colleagues might think I lie about my appointments to have a day off.

Oh stop it.

Whether seeing a consultant or recovering, she took an extra sick day. I am sure Management also view your Consultant appointments as sick days?
There is little difference.
My worry is why she felt your bosses wouldn't accomodate it simply for recovery?

I get where you're coming from, BUT Ask yourself why she didn't feel able to say I need another day to recover. Is the boss an arsehole? Is the company policy stingy? Is she worried about having too much time off sick? Female socialisation paralysing her ability to express a need? Direct your annoyance appropriately.

They won't think you a liar, they will know that she is one. This has nothing to do with you.

The issue here was her telling everyone so openly she lied

You need not worry what others make of your appointments because i'm sure everyone thinks she's most odd firstly for lying then being so casual about it.

That said, the culture of presenteeism so rife in the workplace means that many people feel pressure to attend work when we feel terrible.

Unless you know what the procedure was and how she reacted afterwards you can't in all honesty say she was unreasonable. As an example I had both cataracts done this year and you can drive after 2 or 3 days. But your eyes need time to recover and are sore for a few days, you have to be careful not to knock them.
