Dear (recipient's name),
It's important to focus our attention on business needs while in the office. We only have a short amount of time to accomplish our many assignments. While I know you are a dedicated employee, I am concerned about the amount of time you spend tending to personal issues. The company does not place limits on telephone use, Internet use, or other resources, but we do ask our employees to use their best judgment while at work. Please try to limit your personal business to a minimum, preferably during lunch or other break times.
If you have any questions or concerns, please come to my office. I'd be happy to discuss the situation with you.
Sincerely,
(your name)
