I don't care about my employees at all. Their family lives are meaningless to me, distracting and dull.

However I always pretend to care, always make sure they're well paid, have clear growth in development and pay, feel looked after, that they don't need to hesitate to ask if they need a cash advance or time off for an emergency, etc.

You can be ruthlessly focused and unempathetic whilst also being sympathetic and helping people love what they do. They're not mutually exclusive.
