Do laws work?

In reading and hearing about certain events lately the thought occurred to me that many laws are only laws for some of us. Depending on who we are and how much influence we have makes a lot of difference in the enforcement and consequences of breaking the law. Not being judgemental or whether their actions are right or wrong I look at certain striking factions. From what I understand, they are conducting illegal strikes. As long as I can remember it has been illegal for school teachers to strike. Right now teachers are carrying on strikes in certain school districts. I haven't read anything regarding prosecution or sanctions resulting from those illegal strikes. The students look to those teachers for instruction of course but as teachers they are also a moral guide towards being an upstanding citizen. After all, we certainly don't want criminals teaching our children do we?

So anyway, I simply don't understand the law when it comes to a huge voting block of professionals with almost unlimited cash resources for lobbying and political influence. A legal strike is an important tool in maintaining a level bargaining position improving the work place through cooperation between those bargaining factions. Necessary and useful. However, because the educational system is funded by tax dollars, and technically teachers are civil servants, it is my u8nderstanding that teacher strikes are against the law. If that is indeed the case, what is keeping the government agency in charge from disciplinary actions? I'm just asking? I think kids should be in school without worrying about whether the teacher is a criminal or not. Being taught by someone who has disdain and disrespect for the laws of this country. Who decides which of us has to be law abiding and which does not? But, maybe that's just me.
