I worked at this place for 20 years and the parties were quite legendary.
A couple stories... My manager got drunk and told a few people what he thought. He was a very smart man until that night. His career was going straight up... and then it went straight down. Another time, one guys wife was just sitting there and the story is that without warning, she just started taking her clothes off. One guy got "sucker punched" by another guy... Seems he was dating an old girlfriend and didn't know it.
The picnics, which I used to go to weren't quite as bad, but after two car wrecks one year, they stopped suppling the beer. Then they moved the picnics to the grounds at the plant, which were really nice, but then a couple years later, decided to do them during work hours and make attendance mandatory. They stopped being fun then....
I put 20 years in that place and learned to not make friends at work. We had one guy that worked there and his brother, sister in law, ex wife, new wife, and new wife's mother and brother worked there. At 200 employees, it was hard to hide from each other. Way too many romances, mostly bad and involving cheating, occurred there. A couple of them got caught "in the act" by people walking into empty offices. I had to be interviewed once about a sexual harassment charge where the accuser was just mad that the accused wasn't responding to her advances. I sat next to him the whole time that this was going on and was thinking "WTF?".
I did break my "no friends" rule and met my first wife there. Didn't get serious though until she went to work for GE and I didn't see her every day.
