If an employee has more than one manager, who manages their remote working requests?

In PeopleWeek it is not possible to assign two direct managers to an employee. There is only one direct manager (the person whose name is displayed in the ''Manager'' field in the employee's profile) and this person manages (approves/declines) remote working requests. If an employee has a secondary manager that also needs to see remote working requests, HR can assign the role of "Shared Approver" to the secondary manager. Either the direct manager or the Shared Approver can approve remote working requests (it is not a double approval).
