That is critically important. I've seen unions that try to force everyone including non members to pay dues to the Union, for example local teachers unions. I've also seen union construction workers picketing job sites because non-union workers were doing the job.

As long as the union is completely voluntary for the workers, and management is free to hire whomever they want including non-union workers then I'm fine with them. But, in my experience they are seldom necessary, and often make unreasonable demands.
