Today we received a document from the head off for us to call customer to sign and process it. I am fairly new in my position and I am not sure what to do . so I asked other staff to give it to another more experience person. that person came into my room. SHOUT AT ME! " this is your job, u tell me u dont know how to do it? " and I explained to him i was sick yesterday and i have plenty of work and i am not 100% sure what i have to do since i dont want customer to come to my office, ask me quesiton and i said i dont know. then he said " bloody hell! that's ridicious! " and throw the document to my desk and left the room. I felt really bad really really bad. I didnt do anything wrong and I cant see any problem for " dont know the procedure" . If he dont want to do it, he can always tell me nicely!! And I told my manager about it.. and my manager checked with him, he deny anything! and said " i dont mean it of course and i cant see why she get upset".. i am so pissed!! how can i fight back!!! i really cant stand him anymore.
