If the government isn't enforcing the law, what good is a new law for them to not enforce?
Striking workers were usually on the wrong side of the law though because they were using coercion and force to make every worker to participate in strikes (they could hardly work any other way without laws restricting “right to work”)
Well sure they could. The workers who agree with the strike go on strike and if that's enough of them to put pressure on the employers to meet their demands, their demands get met.
If it isn't, you've failed to convince your fellow workers that the light is worth the candle and if you don't want to work under the terms that they do, you can go work for someone else.
This is mainly a problem when there is no other someone else to work for, but now you're back to anti-trust rather than labor laws.
There's a stronger record of laws preventing a government from acting against workers and ones permitting workers to take matters into their own hands.
