I don't argue that there is anything wrong with the position of trying to increase your pay. We all do it. But I do have a problem with striking to get your point across. Because that doesn't just affect the company, it also affects the consumer. I have and always will believe that no one owes you a job. If you don't like your current position, go somewhere else.
Your argument about contractors is factitious. New employees would suffer the same issues. Being union doesn't mean you are free from accidents or you don't die on the job. It's a non-issue in this argument.
The contract is up and the company refused to negotiate. When you have no contract, one of three things happens:
1. Strike (When the labor is trying to negotiate and the company is not negotiating)
2. Lockout (When the company is trying to negotiate and the labor is not negotiating)
3. Continue work with no contract (While a resolution is being worked out through both parties negotiating)
We have number 1 in this case. Nobody owes a job to the employees this is affecting. We have a strike because the company is not willing to negotiate on anything right now. That is why the USW called in a federal mediator. All you are seeing is the national level of negotiating. Each union contract has local issues that get resolved as well. I have not met anyone that talked about hating their job. It is the opposite as people tend to enjoy what they do.
Being Union is irrelevant as USW people and most contractors belong to a union. New employees do not suffer the same lack of training as contractors. New employees go through a lot of training with the unit they work in along with a lot of safety training before they are allowed to work by their self. This is the key to the contractor part. The contractors do not get this training for the sites they go to. Some of the contractors do not even know what they are looking at, nor do they understand the dangers of stuff they are working on. Even after going through safety regulations for a job some contractors will still do what they want. They get caught, sent off the site (where they go right into another refinery and do the same crap), and then the company sends another person in that does the same crap the previous person did.
These sites deserve less contractors and better qualified workers to do the job right. The contractors are usually maintenance people. There are some really good contractors and then there are some that just don't grasp the reality of the situation around them. The workers for the refinery go through so much unit and safety training that the contractors are not even close to what they do.
