In what ways have unions been both a positive and negative force in society?

Unions have been credited with reducing wage inequality, increasing the likelihood of benefits, seniority rights, and just cause discipline and discharge standards in the workplace. In addition, unions have been instrumental in pushing for unemployment and workers compensation, and decreasing the likelihood of discrimination against workers. Unionized workers are more likely to receive benefits they are entitled to and less likely to be retaliated against by an employer. They are also less likely to quit their jobs. On the other hand, unions are usually associated with lower profits and may or may not improve productivity at a particular employer. Unions also reduce employment growth.
