You get to work all the time you want, whenever you want. The company tells you when peak hours are so that you can take advantage of them. When days have good calls, you make your income in fewer hours.
Work whenever you want, and its what you make out of it.
Inconvénients
Not working all the time, sometimes theres minutes without work and youre waiting for the next call.
No benefits
IT take a while to reply to issues, one time i never got paid for a long call cause no one replied.
