Throwaway for obvious reasons. Several years ago I managed a team of three male engineers and one female engineer (who was younger by the men by around 8-10 years) working on a typical software project complete with tight deadlines and the usual last minute rush. Two days before launch while trying to diagnose a particularly obscure bug the team digressed from trying to fix the bug to griping about which framework was used and why it was a bad decision and how unrealistic the expectations from the client were, etc. As a developer I can sympathize with this frustration so I let it go on for about 15-20 minutes and then I interrupted the group by saying something like "We can act like babies and whine and bitch about the things that are beyond our control or we can accept those facts, put our heads down and push forward like fucking adults". The language was rough, but I like everyone else had worked 60+ hours that week. The team begrudgingly agreed and after a coffee run went back to work.
The project launched on time the next day (Friday) and everything seemed fine. We all went out for lunch, toasted to success and hard work, and then went home early for the weekend.
On Monday, the female engineer didn't show up for work, no call, no email, and didn't respond to phone calls. Tuesday and Wednesday the same thing. On Thursday I received the "hostile work environment" claim stating that I had singled her out and referred to her specifically as a "bitch" and a "baby" and my favorite part, that we used sexist names such as "Factory Girl" in our everyday work environment. On Friday we met with our lawyer who explained that despite having three other witnesses that would testify that her story is shenanigans and that FactoryGirl is a commonly used library that we didn't name, it would be cheaper from a cost perspective and from a PR perspective to settle out of court.
The settlement cost more than the project brought in.
