I'd prefer not to rely on a union.....
I've seen unions at work, and would rather work in a non-union environment. There are so many advantages to a non-union company than there are in places that require you to join a union.
I started out in television broadcasting when I first leftcollege. The commercial television station I was employed at paid less in salary, but I enjoyed working there. I was able to learn much more in a non-union environment because I wasn't restricted to one job, and not allowed to learn other aspects of the industry as was with another commercial television station across town, where there was a union. You were hired for one position, and the union did not allow you to do another's.
I prefer to work for a company which allows me to learn and excel. My belief is that what you do on the job doesn't just help your employer, but can help you. I strive to learn as much as I can on the job. You must enjoy your work, or what is the use of sticking around at a company that you dread to work for, where you can spend at least a third of your daily life.
If find it humorous, that the ones who are a in favor of unions are those that are unhappy with thier jobs.
