i was hired as a replacement for someone, but they havent been fired yet. its one of two people, a coworker or the assistant manager woman. the advertising for the job was very hush hush. i was picked out of like 10 people. im excelling wonderfully, getting a raise 6 days in. they want me to learn everything from the first 2 shifts, and im learning 3rd shift just to know it on my own time. but the thing is.......i dont know who im replacing, and i've met and worked with everyone...how do i not feel bad???
