I was hired as a accounts receivable clerk, but also ended up as a scheduler as well.
My job entailed posting all payments for a particular group of doctors, but also became their scheduler for all surgeries. It was stressful at times to do both accurately. I didn't feel I had backup from the manager at the time, as she did not do scheduling. I was the only one in an office of about 30 women who did this.
It was an interesting job to learn and the benefits were good.
It was stressful keeping account of the scheduling, as well as posting payments, and I don't feel I was paid appropriately for both postitions.
