I saw this in a job posting recently:
No mercenaries! We want people who have been waiting their whole lives to work on something like this.
They don't explain what a mercenary is but from the context it seems they mean people who want to exchange their work for money.It's obviously important for people to enjoy their jobs and be engaged, but anything that reads to me like they want to skimp out on proper pay and working conditions because of how passionate the employees are just smacks of immaturity.
