Hey everyone, first thread. So, let me preface this by saying that I am three weeks into my job as a loader for a trailer and my supervisor today has asked me if I really want this job, apparently, I am not working to his specifications. I have been loading at a pace of 75 to 90/100 boxes per every fifteen minutes which comes around to either 300 to 400ish territory an hour. Now, I just would like to know how I can properly assuage any doubts my supervisor has about my work ethic and work at a better pace? Thank you for your time.
