Working part time at minimum wage 3 days a week for 3.5 hours per day with no break, I was making more in commissions for a day than I was from my actual hourly wage.
There is really little/no opportunity for growth and advancement, people who have been there 8 years get the same hourly wage as the newbies being trained and the ones who started last week.
Managers want you to be aggressive and loud and arrogant on the phone, asking every question in a way that makes the client answer "yes" and not taking no for an answer (unless no is required), they want you to make sales and get transfers at any cost but then when you do so they penalize you for doing this and that and the other thing that does not follow their protocol. If you don't make sales, you lose your job, simple.
Overall training really doesn't cover everything you need to know and the rules are very wishy washy, one manager will say "Yeah that is great keep it up!" and another will say "What possessed you to do that??!?" in regards to the same issues. I once went a month without work and there were times my paycheque was not ready on time.
Fine for a part time activity to kill time for a bit of change to line your pockets but definitely not a job you can depend on in the long run or even in 3-6 months without compromising your sanity and general well-being
