Implementation is always the problem. I know a few people who buy/sell/produce commodity goods and say there is now way that they can afford to follow government regulations... unless their competition does the same. When margins are tight and you have higher labour costs that all your competition... you feel like you are losing (even if you do end up making a profit). Nobody wants to feel like a chump.
Obviously, it is the workers who are truly losing out in this deal, as full implementation would have all the producers raising their prices by a similar amount ( to cover higher labour cost).
For exporters, their competition is Sellers from another country e.g. Vietnam. Exporters from Indonesia cannot just raise their price due to higher labor costs, their Buyers will buy from Vietnam instead. So it's not so simple. Making a profit is necessary, otherwise, how can you pay your worker's severance when the time comes?
