Vantaggi
Great benefits if you can land a job at an office that has a union. Pay was pretty decent as well, great even if you can hit your sales goals. I made $40k - $45K / year and I was not very good at hitting my sales goals. Some coworkers of mine were making well over $50k. If you can stand the job you can do pretty well.
Svantaggi
Worst work I have ever done. Training lasts a few weeks, but it is all based on making sales. 90% of the calls we get are from customers upset with billing or service issues. Mandatory overtime almost every day made for long days of getting yelled at by customers nearly the entire time. Micromanaged constantly, they track every second of your day. I was disciplined for taking too much bathroom time one day. Low moral among workers. It is difficult to stay positive when nearly everyone you work with hates their job.
