My job went on a work conference last month. I was unaware that i was being charged for using the phone at the hotel. At check out i had a $63 balance that they charged to my companies card. Payroll asked me to cover the balance with check/money order at the time i didn't have it. When i got paid the money was deducted from my paycheck w/o any kind of notice. Can they do that without informing me?
