At my last job I couldn't take a vacation without getting peppered with phone calls and emails from desperate employees looking for answers. My bossman was a bullshitter who didn't know anything about how our department actually ran. My co-worker spent his day flirting with the ladies rather than working. So I was happy when I walked out to start my own business. Those two incompetents had to do some work for once.
I hope they didnt scour the job market and find someone else to take up the slack, these people often do! That is a fine thing to do though is start up your own business with your expertise!
