Actually, it does work exactly that way in the real world. Under the laws of most western countries, unless you work in very specific jobs (armed forces, physician, etc), you can form a union regardless of whether you were in one at the time of your contract. It's a very fundamental right that people have. It may not be that way in India, but that's really not relevant to whether it's ethical for players to demand that the plans to ensure their safety are shared with them.
That is so unfair, so as a company owner, the solution to unions would be never to recognize one.
I owe my soul to the company store, eh?
Well, that depends really. You normally have a national union in many cases, and then a local subgroup. The Australian players would rightly consider themselves a subgroup of FICA and the Australian one. The national teachers union (for example) very well intervenes in local affairs if the members in that township ask/need their help. You don't think they'd be involved if a district was potentially dangerous and they didn't share the security plan with the teachers?
