When I worked at a call center a few years ago I made $10.00 per hour and worked most times for 8 hours per day.
On occasion if I was needed I would work up to 14 hours in one day.
So if I worked 8 hours per day I would make $80.00 per day and then if I worked 14 hours per day I would make $140.00 per day.
Depending on how many days in the month I worked 22 days in a month and took home $1,760.00 per month if I worked 8 hours per day and if I worked a few days at 14 hours per day I took home around $2,000.00 per month.
I make much more than that now at my web design and programming job and I take home around $7,000.00 per month and I'm much more happier not having to deal with customers calling into the call center.
