the Bolsheviks didn't have much to do with the small and numerous Russian unions (Russia had a very beurocratically decentralized industry at that point in time) and later fought against them as they mostly joined the white Russian faction

the bolsheviks being backed by the Entente

You mean central powers

and ironically the term Tankie comes from an event where the soviet unions crushed mainly union uprisings against the soviets in Hungary

I clearly stated they opposed unions not reporting to the state. Also the Hungarian revolution was a bit more than a strike. Both the Nazis and the Soviets constructed unions that were organs of the state.
