Pros
Good pay, great peers you really feel like a part of a family, the work environment is usually good unless you work in a location with bad leads. Benefits are good, pension, get to take your truck home if requested, get a raise every year, and a lot of overtime. ETRs are the face of the company so there's a lot of appreciation.
Cons
Very gossipy, ETR position has a lot of liability the retention rate is bad for this position. Training is stressful you have to stop your life for this job to get in and if you fail training they fire you. This is a very good dead-end job. not much room for growth unless you do management and then your no longer represented by the union. Best way to move up and stay represented is to move departments. The customer service positions to move up have a waitlist usually of 5 plus years. you get a raise every year for inflation but it doesn't keep up with inflation.
