Cheri-
I have to ask - what is scrap??? Perhaps I am dense today but I am missing this one.
As far as the process is concerned, I have had trouble in the past as well with suspension. What I did do in the past to remedy (mostly successful, sometimes not) is have them write out an action plan for their own behavior improvement. Often times this led them to document for me the items in which they were underperforming in and acknowledging it as well. This action plan was a condition to return to work; without it, they were terminated. Any violation of their action plan (or policy, etc.) was considered a violation of their committment which was a terminating offense. Most employees will realize this but to aid them I included that language clearly in the performance improvement/discipline area of our Emp Handbook as part of our documented process.
