Easier said than done. My wife tried to find a union job for a year and it was incredibly difficult, and dominated by nepotism. Local unions only offered a handful of apprentice positions per year and there were hundreds of applicants for each. There were standardized exams for entry, but the final test was always a personality interview.

Unions greedily guard membership because scarcity is what drives their salary up, at lest in my area.
