Employee-company relationships are strictly business: service for compensation (usually $). Loyalty here is artificial because at any point the contract is breached (service declines, compensation is inadequate) the relationship is terminated. A business cannot choose to remain loyal to an employee if it means bankruptcy.

Relationships between people rely on more flexible rules: networking, camaraderie, common ground. A psychologist would say that these are a trade of "services" of a sort, but since nothing is inked, loyalty plays a stronger role. Unlike a business, it is not unheard of that a person sacrifice their welfare/life for their spouse/offspring.

It is misguided to expect the type of loyalty in the latter in the context of the former.
