Ok, I know it's not the first time I've asked a question like this on Mumsnet. I think my radar for what is normal or acceptable in the workplace is completely skewed at this point in my life. But here is a recent situation:
Employee A started working with the organisation recently. Employee B has been around a while and has a habit of teasing coworkers. For whatever reason, B was curious about A's age. A wasn't forthcoming. B looked for an opportunity, went to A's things and looked at their driver's license. (This was observed by another coworker. B said they were retrieving something at A's request.) Then B revealed to A what they knew and how they had found out, at the same time revealing A's age to a coworker.
A was upset but didn't know how to respond. Coworker responses were very mixed between exasperation and outrage, saying it was a breach of privacy and confidentiality.
Which would it be in your workplace? A prank gone wrong or misconduct?
