Hi there, @Accting4SmallBiz. I appreciate you joining the thread. Let me give you additional information to resolve your concern.
 

Time tracking users can only enter their timesheets, and the only access they have is to see timesheets and time reports. But, if you want your employees to manage clients, you can add them as Team. Then, they should be able to access the client's profile.
