I have had several warning letters, no suspensions, and 1 attempted termination. The warning letters are gone after 9months. A suspension can be brought up later. The way progressive discipline goes in our area, depending on the issue, is (1) talk with, (2) warning letter, (3) 1 day suspension, (4) 3 day suspension, (5) 5days suspension, termination. Most people correct the problem at atleast after the 1 day suspension. Of course if it's a cardinal infraction, they can fire you immediatley, until panel, non-cardinal is a working termination etc...
