We have a use case where users that does not have view access to an investments but they are allocated to those investments able to see other users allocation in the Staffing module.
Staffing module is meant for those people who need to manage allocations or staffing, normally resource managers or investment managers so they can see it accros people. Resource Manager needs to know and have visiblity what their resources are working on. Tipyical member like this the user would not be granted access to Staffing page as they primary feature is to see who is over/under booked.
This is working as it is intended.
