Its a simple job, a monkey could do it.
You call people and offer them an upgrade on their phone, or offer them insurance, or XM. It can be difficult, considering you can be called names by customers.
manager was pretty sweet, he was versatile and easy to work with.
co-workers were awesome stoned half the times, but that's how they dealt with it. The place always smelled like weed where I sat.
Hardest part of the job, was the windows were never open, and it was a cess pool of sickness. If one person got sick, the whole floor would end up sick. It was nasty.
