Pro Bowl Player
Like I said earlier....you and I are ideologically different here.
Potential employees have the right to decline a job offer for whatever reason they choose. Wages, job requirements, etc.
Employees (once they have learned what they got themselves into or how they are being treated) have the right to resign/quit long hours, workplace conditions.
If they feel their employer is discriminating against them or violating a law they can sue them, report them to OSHA, the Dept of Labor, AG, etc.
The more employees who file complaints the more change happens.
It's not a matter of ideology.
You seem to be missing one small point. Potential cheerleaders only find out all those once they've made the cut after a grueling competition and tryout. The fact that they come so far, and work so hard, only to be told that they're easily replaceable if they make the slightest noise or complain about their miserable working condition, is itself a form of entrapment.
You suggest that they should sue employers who discriminate or violate a workplace law, and I just pointed out that 10 of the 26 teams that have cheerleaders are already being or have been sued. That's more than 1 of every 3 teams.
