10. Make them second-class citizens

Employees who work on-site hear about career opportunities before they become official. They hear rumors of management shake-ups, budget cuts, executive departures, and so on that never are formally announced.

Employees who work on-site are immersed in the day-to-day informal interactions that constantly build and reinforce the company culture. Remote employees are freed from these distractions. Keep it that way so that they stay focused on their work.

Also, give plum, high-visibility assignments to on-site employees. They are, after all, always there when you need them.
