Our bldg works as follows. First Warning letter, no action, Second warning letter for same offense within 9 months, 1 day suspension, third warning letter for same offense within 9 months of the first letter, 3 day suspension, 4th warning letter within the 9 month time frame, 5 day suspension, 5th warning letter for same offense within 9 months, results in termination. We have had several preloaders with 15 or 20 warning letters for misloads within a 9 month period work fired. It works out well for the Union members as it makes the warning letters more then worthless. As stated in previous posts if you fight a warning letter in our local, more often then not it will be dismissed.
