Interesting! No it wasn't me mate! I'm not a lawyer. But I have had positions of responsibility in various big corporations and I've seen a big change in the workplace over the years. There were times when I'd have had similar banter with staff, but absolutely no way would I risk any of that now, not even with my best mates on a night out, never mind in a company meeting. I won't bore you with the details, but I once had a member of staff claim I'd said something in a meeting which upset her. There were 8 other people in that meeting, no-one else heard anything. She was not a natural English speaker, so there may have been some misunderstanding/misinterpretation of what I'd said. But she took it all the way to HR. HR reached an agreement with her, and paid her off to leave. A year later she was re-employed again and a year after that she was up to the same old tricks with another manager. - claiming something had been said in a meeting which upset her - and claiming compensation for not being able to work there anymore.
There are some dangerous people out there!
