One of my dearest friends has been off work for the last 4 weeks because of a digestive fungus. Her health is not great in general, she tends to catch bugs and viruses very often, so she has taken quite a bit of time off work in the last year, but nothing unreasonable. She has a relatively entry-level professional job at a big company.
Yesterday I called her to ask her how she was, and she said she is not doing well at all, in fact she is getting worse and she has terrible issues with extreme fatigue and headaches. As a result, she decided to take another 2 weeks off from work, for a total of 6 weeks off. She hopes she will be able to go back to work at the beginning of May.
Then she told me she is going on holiday to Greece next week as she thinks unplugging under the sun will improve her health. Honestly, I don't know if going on holiday will improve her health or not, but I am bit concerned that she will post on social media from her holiday (she is very active on social media) and that she might have serious trouble at work if her colleagues see that she went on holiday while being on sick leave. I know for sure she is connected to several colleagues on social media.
If I was her manager and I found out she went on holiday, I would seriously question whether she was really sick or just taking the piss. In fact, at my old job a colleague received an official reprimand because she took a sick day to care for her sick child and then posted a pic on fb on the beach with her child. Her manager assumed she lied about her child being sick and that she just wanted a day off.
So, AIBU to warn my friend to be careful about posting from her holiday? Or should I mind my own business? I am concerned she might take offence and think I am criticising her for going on holiday, when in fact I am just really worried there might be serious consequences if she is not careful.
