I had asked to be scheduled for weekends only, and hadn't been able to work due to sickness or schooling. They tell us if you can't go to work for any reason, email staffing. I email them I can't go to work because of cultural reasons, and they take my email as a letter of resignation.
They also don't pay in full, even though they don't take taxes off of your paycheck. Any attempt to inquire pay breakdown is met with many excuses.
