Two things generally tend to happen here in the summer:
(1) The path of least resistance is zombification, and the zombies generally take over
(2) The bosses are away and donít very care much what is happening back on the plantation (provided anyone trying to damage it is killed), since all the important other people (i.e competitors etc.) are generally away also.
Combustible combination really: Pent up tensions rise to the surface, and people have time and opportunity to work them out. But turning on each other is acceptable.
Things get whacked back into shape (for the survivors) after Labor day.
Welcome to the Mad Max/Elysium/late stage capitalism.
