I'm guessing most everyone's familiar with some variation on this phenomenon, but let's define a term real quick before I get down to business:
"Black Eye Season" is the nebulous off-season of businesses (or for that matter cities or states) that operate year-round but are largely seasonal.
During the long, dark, cold winter when things get a little sleepy people have a lot of time on their hands, a portion of which inevitably ends up devoted to grousing about working conditions in the long, dark, cold winter, and concocting grievances (both reasonable and un-) against co-workers, management and the cruel, cruel universe at large.
Those of you don't work in an industry like this can just picture Jack Nicholson in The Shining. Well-adjusted people don't live here anymore, Mrs. Torrance.
Good then. Let's go.
