Once the "left-wing" communists are in charge, do they allow trade unions?

Of course not. Just another point of similarity between the fascist and communist forms of Socialism.

Hmm, and what happened to the Mensheviks (democratic socialists) after the Bolsheviks took power in Russia? They were also purged. And the Troskyites after Stalin came to power? Also purged.

Once they get power leftists will not allow any other potential political opponents no matter how trivial the excuse to purge them is.

As an aside, the nominally anti-fascist left in Germany was told by its masters in Moscow to not oppose Hitler when the Soviets and Germans were allied. This is true of communists throughout the west too, of course, who took to claiming Churchill was a warmonger persecuting poor Hitler for no good reason. My how history repeats itself.
