“The quitting economy: When employees are treated as short-term assets, they reinvent themselves as marketable goods, always ready to quit” should remind you of “Company loyalty is dead. Switch jobs every 18 months to two years.” It’s not employees who killed company loyalty: employers did.
Regardless of who killed it, it’s gone and isn’t coming back. Structure your career appropriately. Whenever someone talks about the virtues of loyalty to a company, remember that they’re really trying to take money out of your pocket.
