Burnout is caused by resentment
I'd agree.Every time I've quit, it's because I felt I was repeatedly getting the short end of the stick, and management was expecting me to roll over every time I brought such things up.I quit my first job at 15 1/2.  I worked at a Wal-Mart during the summer to buy a computer.  I covered 200% more departments than I was hired for.  I never took a day off, despite coworkers just not showing up so they could go to the beach.  My department manager LOVED me.  After my 3 months, I got $0.24 of my $0.25/hour potential raise.  I asked the store manager responsible as to why I didn't get the other penny.  His answer was utterly asinine.  He expected me to go back to work, understanding.  Instead, I called my mom and went home, never to return.The next two jobs I was vastly underpaid.  I knew this because vendors, contractors, my own boss and even the office manager told me, quite literally, that I was getting screwed.  I was told to man up in response to crappy raises.  Instead, I found better jobs that were willing to give me 25-30% more just to walk in their door.At one place I blew the doors off of all expectations.  I qualified for well above the normal bonus.  32%.  I was denied because in order to get the bonus I had to have been there since July 1st.  My start date?  July 3rd.  It's not like it wasn't going to be pro-rated, or cut in half.  I simply wasn't going to get it.  32% of my salary was a chunk of change large enough to buy a family sedan, cash.  Obviously, I made an issue of it.  I had vacations denied and had already dealt with that.  When a partner said that there was nothing he could do I gave him my curt two-word response and walked out the door... to basically get my lost bonus half as a signing bonus, and the rest over the next year.Employment is a two-way street, and when you also decide to make it known that my contract is "at will", be advised that I'm aware that I can just not show up anymore, just to make the point.  And even though I won't do that, I know I could.  At the very least I ask that you demonstrate it, and ensure that I feel appreciated.  If you don't, don't be all that surprised when I jump ship at a moment's notice.  It's not rocket science -- put your best foot forward, and if you can't, explain clear as day why you can't.  Show some humility, and don't expect me to simply sit there and take it, especially in this market.  I'm pretty good about making my happiness unknown, and giving organizations months and months to respond before I finally depart.  However I've worked with folks that their mentality towards burning bridges is more akin to Aliens: they don't burn bridges -- they nuke them from orbit, just to make sure.People do business with people they like, and your employees are not exceptions.
