You are loyal to family, friends and country if said entities are worthy of it - i.e. if they reciprocate it. I can think of plenty of reasons why someone would choose not to be loyal to family. Someone I know is gay, his father never accepted, or even respected that, during an entire lifetime, and the guy didn't even show up to his funeral.
If a company shows genuine respect, compassion and, indeed, loyalty to an employee, there's no reason they couldn't be shown the same in return - even if it's ultimately for the profit of the company (if said values are expressed, the profit of the company should also positively reflect on the profit of the employee).
