Sorry you were fired instead of someone who had more time than you, but you think your better than.. F.Y.I. Senority is the way the vast majority of American companys determine who is going to be layed off...
Also, remember noone thinks of themselves as a worthless employee, but people do tend to look at others that same way.. Think about that for a minute next time before you start telling us how you are better than the other guy
