Sorry. I should have said he agreed with Walker that they should be limited in the the rights that private sector trade unions enjoy.
I don't think saying he agreed with Walker is accurate.
No, Stalin didn't outlaw trade unions. There were two factions, one that believed that unions should be militarized, the other (the unions led by Alexander Shlyapnikov) that believed that unions should run the economy. Neither side outlawed unions, it just didn't happen. The unions got stronger under the Soviets and under Hitler. This was the Дискуссия о профсоюзах (pronounced deeskoosiya o profosoyuakh which means the Dispute about the unions).
Just saying "Stalin didn't like unions" flat isn't true. Nor is it true that Hitler was against unions. "All of the most dictatorial" regimes flat didn't outlaw unions. (Although Hitler did outlaw Freemasons).
Damo: slapping the label "union" on an instrumentality of totalitarian regime doesn't make it a union as we understand the term. They all outlawed unions as we understand the term and co-opted them.
