Almost always the pendulum swings far in the opposite direction. Are unions needed, I think so....have they abused the privilege...heck yes.
I was in a union for 14 years, or I should say forced to be. That should throw up a red flag having to be forced to join. The union stewards got super seniority, the officials went on major boondoggles around the country. When I worked at McDonnell Douglas using portable laser calibration equipment, I had to sneak the equipment in my trunk from building to building so a Teamster wouldn’t see me, or they would file a grievance against me. I stopped counting the grievances that they filed.
I do believe that things would eventually swing too far the other way if there weren’t unions though.
As far as the goofball writing bad reviews, I think what wrench said is true. People take reviews with a grain of salt. Anytime I read a review on a restaurant I can usually tell if they are over the top.
