Office sharks
I really like this post (a), but it's sorta hard to excerpt. Here's the beginning:
Some species of shark are obligate ram ventilators – having lost the muscles required to pump water through their gills, they must keep moving in order not to asphyxiate. Unfortunately, the obligate ram ventilator is also commonly found in the modern American workplace.
Whereas some workers seek the simplest, fastest or most efficient solution to a problem, others will feel that they need to fuss, writhe and intensify tasks as if their lives literally depend upon maintaining a certain velocity through the water. Don’t mistake this for effectiveness or passion – the obligate ram ventilator’s pathological need to work makes her a danger in the workplace.
