Macau gaming operator SJM is dealing with massive and unprecedented employee discontent.

Life as an SJM croupier has changed dramatically since gaming liberalisation but workers feel it is not yet to the same standard as the new operators.

Hundreds of SJM's front-line staff took to the streets again last month demanding higher pay, better benefits, more incentives and better career advancement protocols, in what was the second protest in the same number of weeks.

Despite the fact that industrial action was triggered, the workers maintain that they want a peaceful solution.
