A burnout is ...When a person starts taking the "Routines" as "Specialized jobs"... out of sheer frustration !
An example ...
That instead of taking the routine Lift ride to the ground floor ... one starts taking the Emergency Exit stairwell !
Because, Boredom of Routines ... reaches a saturation point in almost every one of us ... because, by nature, we need Change ... but if, or when we cannot change the boring routines into something productive or interesting ... the will, to "Do" leaves us.
Morale, on the other hand, has more to do with ones "ambience" ... "surroundings" ...than with the "Normal" job related Routines ...
An emotionally weak employee will be easily demoralized by the comments of Competitors, or, by the pickings of an inconsiderate ... slave driver type of boss.
Therefore, it can be said ... that the difference between Burnout and Demoralization is; that while Burnout, is essentially Internal ... Demoralization, is usually an Externally induced Feeling in a person.
