Corporate loyalty is a two-way street.
In medieval times, the vassal paid homage and swore fealty in a commendation ceremony, and the lord granted him a fief. The vassal had a duty to aid his lord, and the lord had a duty to protect his vassal. The vassal gave loyalty, and got a secure income in return. It was a permanent relationship. To dissolve it, you had to use an axe, rather than a pink slip.
Corporate loyalty died when management culture forgot that the company owes duties to its employees in addition to its shareholders. Defined benefit pensions became defined contribution retirement plans. Then the employer contribution disappeared. Health insurance plans dwindled from all medical expenses paid to you paying 80% of the premium, $30 co-pays at every turn, and deductibles that are met midway through the twelfth month of the plan fiscal year, then reset. Training programs evaporated. Severance packages got smaller, or vanished. Even the amount of notice I get whenever permanent layoffs are to occur has become days, rather than months.
So there are no more loyal vassals. We are all mercenaries now. I'll start sending out resumes if I so much as notice that the building has a new janitor.
H. R. tells new hires:
"How great it is to work here!"
Give me cash, not lies.
If corporate loyalty is dead, it is because corporations have killed it.
