Have you ever witnessed something sad at work?

Many years ago I used to work with this foreign guy. He was very young and we were doing a heavy manual role in a ceramic warehouse. I can remember he was so p*ssed off at something one day he threw a tile all the way across the aisle. The moment was too heavy for me to say anything

Years later thinking about it, he's a young kid thousands of miles away from his family, breaking his back for around £5 an hour (2012)

I guess thinking about it randomly made me feel sad. Over the years there's been a few odd incidents. One lady recounted to me how she was in a low key unhappy relationship and how she coped. Another was a refugee guy who'd been forced to leave home alone to save his life. That was a quiet summer's day and we were alone in the office when he suddenly started telling me his story. I didn't get along with him generally as he was a bit bossy but he was damned good at his job. It made me see him in a different light. I had a boss who started telling me about his stepdad killing himself on a winter's evening when we were alone in the office. Most of these people have moved on but I think about the struggles people come to work with and think we should be kinder to each other.

Interested to hear stories first and second hand.
