Returning multiple cross referenced values.

There has to be a better way to do this?
This query returns four records, two of which are incomplete. I need to return a single complete record

     isnull(t1.[EMAIL], '') [Safety_Email]
    ,isnull(t2.[EMAIL], '') [Eng_Email]
    ,isnull(t3.[EMAIL], '') [Shop_Email]
    ,isnull(t4.[EMAIL], '') [Fore_Email]
    ,isnull(t5.[EMAIL], '') [Qc_Email]
    ,isnull(t6.[EMAIL], '') [Drft_Email]
    ,isnull(t7.[EMAIL], '') [Mgr_Email]
    ,isnull(t8.[EMAIL], '') [Parts_Email]
    ,isnull(t9.[EMAIL], '') [Ship_Email]
  from [WorkOrder] w
  left outer join [EMP_MST] t1 on w.[SAFETY_INI] = t1.[INITIALS]
  left outer join [EMP_MST] t2 on w.[ENG_INI]    = t2.[INITIALS]
  left outer join [EMP_MST] t3 on w.[SHOP_INI]   = t3.[INITIALS]
  left outer join [EMP_MST] t4 on w.[FORE_INI]   = t4.[INITIALS]
  left outer join [EMP_MST] t5 on w.[QC_INI]     = t5.[INITIALS]
  left outer join [EMP_MST] t6 on w.[DRFT_INI]   = t6.[INITIALS]
  left outer join [EMP_MST] t7 on w.[MGR_INI]    = t7.[INITIALS]
  left outer join [EMP_MST] t8 on w.[PARTS_INI]  = t8.[INITIALS]
  left outer join [EMP_MST] t9 on w.[SHIP_INI]   = t9.[INITIALS]
  where [JOB_NUM] = 115390

Thank you in advance,

Try this:
     max(case when em.[INITIALS] = w.[SAFETY_INI] then em.[EMAIL] end) AS [Safety_Email],
     MAX(case when  em.[INITIALS] = w.[ENG_INI] then em.[EMAIL] end) AS [Eng_Email],
     MAX(case when  em.[INITIALS] = w.[SHIP_INI] then em.[EMAIL] end) AS [Ship_Email]
  from [WorkOrder] w
  left outer join [EMP_MST] em on
      em.[INITIALS] IN (w.[SAFETY_INI], w.[ENG_INI], w.[SHOP_INI],
          w.[FORE_INI], w.[QC_INI], w.[DRFT_INI],
          w.[MGR_INI], w.[PARTS_INI], w.[SHIP_INI])
  where [JOB_NUM] = 115390
  group by [JOB_NUM]
