What Is the Difference Between a Secondary Strike and a Mass Industrial Union?

The soviet union, which in many ways controlled what was happening with communist with cpu s a, basically said, we need a labor peace because we need to support the war effort. And so that's when union started a signing contracts with no strike clauses. They started um agreeing that they would no longer strike and start agreeing to things like speed ups. But i think that we still don't, i think it's so far away from living memory of what a real strike wave is,. where people would go on strike in one factory and in the next factory, in thenext factory next herry.
