Sales assistant for mobile company's

[EBII Fairmont]

Hi people,

I have had enough of current management at work. I worked ridiculous shifts before exams, so I could get a month off. Now they won't let me have the weekened off so I can study for my monday exam.

I have decided that I am going to start looking for new work.

Does anyone here work in optus, vodafone, 3 or telstra shops. I just want to know:
what are the hours required like?
is is commission based?
is it a good enjoyable job?

If I think of anything else I will also ask.

Thankyou all in advance.
Bill
