Any employee should show zero long term loyalty to an employer in almost all cases. As soon as it becomes convenient, a company won’t hesitate to drop you like a rock, especially if it can save them a dime.
Ask a lot of boomers how that whole loyalty thing has gone over the last 5 or 10 years. My neighbor worked for the same company for over 30 years. Couple years ago, end of the day on a Friday, they laid him off, that was it. 30 years... laid off on a Friday afternoon, no notice, nothing.
The double standard of employer and employee loyalty in the American workforce is absolutely outrageous. The employee is supposed to give at least two weeks notice, preferably longer, while the employer can kick your ass out the door with not notice and that’s it.
At the end of the day, I have to do what’s best for me. I know if my employer could find a way to axe everyone tomorrow, they would.
