Re: listen.
The public unions (and others) in the U.S. are basically an arm of the Democratic Party. In other words, at this point they're PART of the government when Democrats are running things.
In the private sector, about seven percent of workers are unionized, a number that has been steadily dropping over time, which means about 93 percent of the employees in the private sector are doing all right without them. Almost everything you hear about how essential unions are is from unions and their allies.
The first example you give in a link is based on hearsay from a union leader. I don't think you read the second one.
