I can see where the safety aspect of the union could be beneficial, especially if the company, or certain employees of the company, were committing unsafe acts, but a safety committee couldn't have prevented that collapse. I have a safety committee at my landfill, and we aren't union. You wouldn't believe the safety and HR training that I am required to attend every year. That's an operations issue, and ultimately the operations of a landfill are the call of the manager. If the operators were told to do something that was unsafe, and they knew it was unsafe, then maybe a committee would have helped. If the operators didn't know, nothing would have changed. It's not the responsibility of the operators to safely construct a landfill, that's not what they are paid to do. There are operations plans, fill sequences, that are designed by engineers that have to be followed. The engineers don't communicate with the employees, that's what I am paid to do
