DECLARE @Table TABLE(
        Supervisorid INT,
        Empid INT
)

INSERT INTO @Table SELECT 3, 4

SELECT  @ID = 3

;WITH Vals AS (
        SELECT  *
        FROM    @Table
        WHERE   SuperVisorID = @ID
        UNION ALL
        SELECT  v.SuperVisorID,
                t.Empid
        FROM    Vals v INNER JOIN
                @Table t    ON  v.Empid = t.Supervisorid
