This wasn't on ME per se, but it was pretty upsetting for me and others.
I work for my state government. When I'd been there about a year, they decided they needed to do layoffs, and they were very hush hush about which departments would be affected. I had the least seniority in my department, and our union has a last in/first out policy.
They decided to eliminate all of the administrative support staff, including our administrative support worker. They got the calls first. Then, one of my co-workers, same job title as me but a little more seniority (second lowest after me), picked up her phone, talked on it, and then hung up and said, "guys, I got the call, I'm being laid off." Of course I was upset because I knew if she was being laid off I was too. I'm the primary breadwinner in my family, so losing my job would be a real blow. My coworkers were hugging us and telling us how sorry they were - the she burst out laughing; she'd made it up!
It was very insensitive to me, but it was especially insensitive to our administrative support worker, who was being laid off, who HAD gotten that call, and sat right next to this woman! That was about 9 years ago, and I still shake my head at that behavior. Just awful.
