When the workers go on strike
When the workers go on strike, the replacement workers will be in the form of contractors. My mother's job with the school district just unionized. They should really bargain for job security as opposed to benefits and pay. I think one industry that should unionize is the amusement park workers as many theme park workers are subject to the summer heat, harsh working conditions, and long hours. My former job at a theme park was exempt from overtime laws and working 50-60 hours a week (open to close) at minimum wage has its challenges.
Also, structured employment programs for workers with disabilities can pay as little as $1.25 an hour as there is what is called the special needs minimum wage.
All of my CPE (including my EMTA) is customer owned. The only Comcast owned equipment in my house is the CableCards in the two TiVO boxes I own.
