Find Employees in the Same Position with Multiple Employees Occupying the Position

Hi All,

I am trying to develop dax logic to identify those employees that have been in the same position for 6 weeks (42 days) where the position has multiple employees (incumbents) occupying it. 

I want the logic to return 1 if all conditions are met as per the switch statement.  I think I am almost there, but I think the issue is the many calculate functions are not working together somehow.  Any advice appreciated.  thanks.

IncumbentInSamePosition>6Weeks(WithMultipleIncumbents) = 
VAR PosNum6Weeks = 
CALCULATE(
    CALCULATE (
        MAX ( FACT_EmployeeDetails[Position Number] ),
        DATEADD ( Dim_Date[Date], -42, DAY ),
        ALLEXCEPT (
            FACT_EmployeeDetails,
            FACT_EmployeeDetails[Occupancy Date],            
            FACT_EmployeeDetails[Personnel Number]                     
        )       
    ),
    FACT_EmployeeDetails[Employee Status] <> "Terminated",
)
VAR PosNumHasMultipleIncumbents = 
    CALCULATE (
        COUNT ( FACT_EmployeeDetails[Personnel Number] ),        
        ALLEXCEPT (
            FACT_EmployeeDetails,
            FACT_EmployeeDetails[Occupancy Date],
            FACT_EmployeeDetails[Position Number]            
        ),            
        FACT_EmployeeDetails[Employee Status] <> "Terminated",
    )
    
VAR CurrentPosition = 
    CALCULATE( 
		max( FACT_EmployeeDetails[Position Number] ),	
		ALLEXCEPT(
			FACT_EmployeeDetails,
			FACT_EmployeeDetails[Occupancy Date],
			FACT_EmployeeDetails[Personnel Number]
		),
        FACT_EmployeeDetails[Employee Status] <> "Terminated",
	)    
    
RETURN
    
SWITCH( true(),    
        CurrentPosition = PosNum6Weeks  // Position Number equals position number 6 weeks ago (42 days ago)
        &&         
        PosNumHasMultipleIncumbents > 1 //AND Position has multiple incumbents
        , 1
)
