Comment that's not what union are (Score 1) 121
Labor Union do not provide exclusively labor to companies. What they do is have the power of collective bargaining, job protection, safety - which is utterly different to being "exclusive provider of job".
You may confusing normal labor union, with hiring hall union (e.g. in construction/actors/voice actor). That is a widely different type of union. Most union are NOT hiring hall union.
Feel free to correct me.
