Yes, it is the case that the presence of a union can provide cover for employees who are incompetent, lazy, or both. This doen’t mean that management is helpless and can’t do anything about it. What it does mean is that they can’t be lazy, slopply, or abritary in how they discipline employees. Rather, they actually have to show cause for why an employee should be disciplined, or even terminated. I really don’t see what is so unreasonable about this, and I don’t understand why some people have such a hard time believing that management is sometimes lazy, or incompetent, or prone to playing favorites.
I have worked in a union shop before, and I’ve seen it all. I saw employees (union and non-union alike) who deserved to be fired and weren’t–sometimes it was due to taking advantage of union representation, sometimes it was due to knowing how to do just enough not to warrant attention in a workplace with several hundred employees, sometimes it was due to being friends with the right people in management, and sometimes it was due to nothing other than incompetence and/or laziness on the part of management. I also saw employees (union and non-union alike) who deserved to be fired and actually were, in spite of union representation. In such cases, they got fired either because their offenses were so serious that even a fool could see they deserved to be fired, or because the manager making the termination decision actually did his or her job in demonstrating that the termination was warranted. I’ve also seem employees who were targeted by unscrupulous managers, sometimes to the point of being unfairly disciplined, or even terminated. In such cases, sometimes union efforts resulted in people getting their jobs back, and sometimes not.
On th whole, it seems to me that unions largely exist to keep management honest. The relationship between employer and employee is one that is generally not a relationship between equals. In most cases, the reality of economics dictates that the employer is the more powerful party in the relationship. Unions serve as a check on the power of the employer. Does that sometimes create a new set of problems? Of course, unions are made up of people who are sinful. Of course, if it were not for the fact that the people who run companies are also sinful, there would be no need for unions.
