job musings

i begin to wonder if i got canned without being told.  i had one slip in the almost three years ive worked for the guy and havent had a show since.  the next week some new guy takes over(and doesnt do all hes supposed to but hopefully he learns)  then i was told to keep a day open for work and wind up spending that day home twiddling my thumbs.  what the hell is going on?
