Everybody who has ever had cancer (or suffered any scary health event) remembers when they first noticed the odd little clue that something was awry. Or an aircraft pilot who thought he saw an odd flicker of a gauge needle, or noticed a strange little vibration minutes before the routine plane ride became a nightmare.
Since time immemorial, the relationship between employers and employees have often been a bit strained.
Once upon a time, I remember many businesses had an office door that read: "Personnel."
Beginning about thirty-plus years ago, all those signs were slowly replaced with the words that read: "Human Resources."
The employee/employer relationship has gone to

really fast since then.
Coincidence?
