For all the stories saying "I was forced to do 80-100 hour weeks for months", I wonder how often these employees say "I'll do it for one week because I want to support this team, but I'm sorry I have other obligations beyond that that limit me to working only a regular week with an occasional 2-3 hours overtime if needed". Maybe I'm biased but I have trouble envisioning an environment in which a manager would fire somebody for that.
