I am a new hire. Anyway My sup has been tricking while I have been loading by putting misloads mixed in and I haven't had any real time to study the zip codes because there is so much work to be done but I look at every package. Anyway at the end of the night I had to initial some places under something that said salt d-something. What does this mean. Am I in the boundaries to where they will fire me for misloads? I am still trying to learn them
