A colleague has been off work sick for almost 6 months. She was assaulted at work (by a client) and it's not surprising she isn't finding it easy to return, although employer has really tried with support and counselling etc. The expectation is that she probably won't return, but she'll use her full sick pay entitlement first.
Although employer has put some cover in place, they can't replace her permanently until/unless she leaves and temp cover is proving difficult to source/unreliable so colleagues are having to pickup some of the slack.
Meanwhile, her social media feed, which many colleagues are party to, is full of all the wonderful ways she's using this time. She's currently on her third holiday in the sun since her absence began.
She is/was well liked and there was tremendous sympathy for her when this all happened, but that is wearing thin. No one expects her to stay indoors for her whole absence and logically everyone knows that getting out and about will be helping her recovery, but would you expect a bit more tact with the posting?
