Recommendations for a trade union

Hi Everyone,

Can someone recommend me a trade Union which foreigners can join ? And preferably cheaper ones.
My interests would align in tech, computers or arts /crafts.

Cheers.

The Peoples’ Liberation Army and Coolio’s Momma Union for Corndog Vendors at the Oldevai Gorge in Tanzania (PLACMUCV-OG). I met the head person and he is the African Che Guavara

Which union are your colleagues members of?
