You'll also be fined for failing to deliver on the contract if you take time off due to sickness. You'll be sent home without pay when conditions find the mail room short on mail, but you are required to be available for work the rest of the day, just in case the delivery was late. You'll be repeatedly told how much more convenient this is for you.
