A Day in the Life

You arrive at GlobalTech Solutions' downtown office in Chicago, clocking in at 8:00 AM. The mailroom is quiet. Your first task is to unlock the large security cage where the morning delivery sits. Using a sturdy hand truck, you wheel in several canvas mailbags and boxes. You set up your workstation, donning gloves, and begin sorting the bulk incoming mail into initial department bins. The smell of fresh paper fills the air as you ready your automatic letter opener.
