Ventajas
Ideal for college students or those with another part time or fulltime job. There is a great deal of flexibility where you get to completely make your own schedule as long as you work at least 16 hours a week. They're open from 8am to 10pm during the week and sometimes on the weekends depending on call volume, so it's very easy to make a schedule that works for you.
Desventajas
Pay starts at minimum wage and can increase if you're extremely productive, but it's difficult to reach the threshold of productivity that ensures higher pay. The break policy is terrible. If you log out for more than 2 or 3 minutes, you're locked out for 30 minutes. So no going to the bathroom unless you schedule it before hand (who does that?), no checking your phone if there's an emergency going on, none of that.
