You won't change the system - the company will always get their way. Unions don't work in Hong Kong, hasn't that already been established?! It's how it's worked here for years - love it or leave it.
You will never see executives in Hong Kong kowtowing to staff demands. It just isn't in their fibre to do it and I doubt the thought would have even crossed their minds.
Actually you are wrong. It is just that WE can't get it right. Staff unions of company like Watsons Water and some other local companies have gone on strike before and basically got what they wanted. Remember when the construction workers in HK all stopped working a while back? They got pretty much the pay rises they all demanded.
