Employee was trying to catch the men on 3rd shift before they left the plant, because they didn't have to report for work that evening. He got out of Unit #220 & shut his finger on his right hand in the driver side door. He didn't miss any work because he wasn't scheduled to work on Friday, 10/23/09 & he returned on his regular shift on Sunday, 10/25/09 at 11:00 P.M.
