User wants to know if project managers get to see the cost information of employees and projects in Core.
The Security feature in Core is very granular and provide permissions to every module and report. You can disable the ability for any logged-in user (employee, vendor or manager) to see any cost-related information. The best way to handle this is to customize a security profile to hide cost rates and then assign that profile to your users. The other option is to take the security profile of each user and then customize it.
