Actually you could in fact take this a step further into behavioral theory, if you consider workplace satisfaction derived from doing work versus other sources (football tables etc). It could be said that too much satisfaction from the &quot;other&quot; sources &quot;extinguishes&quot; (or overrides) the satisfaction derived from doing the work.<p>Kind of like that classic experiment of the rat who is given a regular dosage of cocaine and soon starts to neglect any other activities beyond the consumption of cocaine.
