The thing you would be most interested is the pay. An entry level Advocate makes around 40k. a promotion will get you around 5k. That is not enough for the job. A supervisor is given a 10k raise from where they were, and can get a 5k raise in 6 months if management has decided you did well. This is still not enough for this job.
This job will ask the world of you with little training, in a tight turn around time, and mistakes are harshly punished regardless if you were trained on it or not. The training is 3 months for a job they consider takes a year to understand and be able to function within. Due to the high turn around on employees there is often the push to put people on an active account before their supervisor or manager believes they will be successful, putting everyone in a lose/lose scenario.
For a supervisor: The company encourages and expects a micro manage mindset, you will have a full (read 3 peoples) work load, be expected to perform reviews, be on call 24/7 (they do provide a phone) to answer to irate truckers across the country at all hours. You are not reimbursed for these hours.
As a supervisor you are forced by management to put your employees into lose lose scenarios and then are held accountable for the end product.
For me, I was put into a situation where my employees and I had a good relationship but the company would not let me help them, as a supervisor should, when they needed me.
When the employees advised of their plans to leave/retire and I asked what the plan was so i would not be covering 4 jobs with no compensation or benefit I was told their was no plan, and as i did not have a solution, there was not one, and i would have to deal with it.
