Slight over reaction ??

My work roster is complied and published electronically - but as any computer programmer knows - 

Computers don't make mistakes people do

but we mustn't complain about the roster as it is unprofessional and is taken as a person insult to those completing the roster.   Apparently I'm not going to another location to work - the computer has made a mistake so I have been upset for no reason at all....

I'm not fuming about this, just learning to chill
