  That has always been a problem in the work force for as long as I can remember.
  Re: security there are some places that are just "chair
warmers", just being there in case anything would happen.  People see
that as easy money but don't realise there is more than just sitting there.
 A lot of responsibility, such as explaining why something happened while
one was there and they didn't know till afterward.  As if we are to be in
several places at once.  As well as a lot of boredom at times.
  Then there are that active places, where one is actually up and around
and doing things, and some places require armed guards.  And one has to
supply their own gun, training, etc.  Unless one is certified to begin with
that can be costly.  Out of about 250 in my company only about 30 are armed
and at special places.  And the only time the sidearm is seldom out of the
holster, much less fired and that's on the practice range 99.99999 per cent
of the time.  Thankfully.  (The same with the cops I know).
   But there are some lousy jobs in security as well, such being out in the
weather for hours at time, few bathroom breaks (you learn to hold it in),
dealing with the public, etc.  Not to mention long hours.  One might be
ready to go home then learn their relief isn't showing up and have to pull
a double.  Or having to stay until someone is found to take over that shift
or the person simply never shows up and can't be found (and either have
their phone off or don't answer).  There have been times a captain will go
to the persons home and almost literally pull them out of bed.

  They want high paying, cushy jobs right off.
  I knew many students over the years who all thought once they had that
piece of paper they could walk into the business of whatever their major
was and be made CEO that first morning.
