Remember one thing about unions, they could not exist if the large companies would treat the employees fairly and pay a fair wage. How True it is.
Was true a very long time ago, but most of the worker protections that the unions originally fought for are now incorporated into State and Federal worker protection laws - - these days when you have teacher union leaders making 350k to 500k when the teachers they represent are woefully underpaid I think unions have become more about enriching their leaders than actually doing much if anything for the employees
and the biggest joke of all are government employee unions - - why should government employees need protection from the people when it is the government that makes the very laws that already protect them?
