Get distinct values from a query having multiple union values

actually i need the distinct values from multiple union statements but i do not getting this.

here emp_id of 578 has weekend and absent in different rows which i need in single row.

my code goes like this.

 select [Employee Name],emp_id,holiDAY, leave,absent,weekend from ( SELECT *FROM ( select view_emp_info.emp_fullname+' '+'('+''+CONVERT(VARCHAR(50), (view_emp_info.EMP_ID)) +''+ ')' as [Employee Name],view_emp_info.emp_id,tbl_emp_forceduty.Holiday_Name as 'HOLIDAY' ,''AS LEAVE,'' AS ABSENT,'' AS [WEEKEND] from view_emp_Info inner join tbl_emp_forceduty on view_emp_info.emp_id=tbl_emp_forceduty.emp_id where ondate=@date and view_emp_info.BRANCH_NAME=@branch and view_emp_info.emp_id not in (Select emp_id from tbl_emp_attn_log where tdate=@date) and view_emp_info.status_id=1 union select view_emp_info.emp_fullname+' '+'('+ ''+CONVERT(VARCHAR(50),view_emp_info.EMP_ID) +''+ ')' as [Employee Name],view_emp_info.emp_id,'' AS HOLIDAY ,isnull(tbl_org_leave_log.leavetype,' ') 'LEAVE', '' AS 'ABSENT',''AS 'WEEKEND' from view_emp_info inner join tbl_org_leave_log on view_emp_info.emp_id=tbl_org_leave_log.emp_id where leave_date=@date and view_emp_info.BRANCH_NAME=@branch and view_emp_info.emp_id not in (Select emp_id from tbl_emp_attn_log where tdate=@date) and tbl_org_leave_log.Taken='0.5' and view_emp_info.status_id=1 union select view_emp_info.emp_fullname+' '+'('+ ''+CONVERT(VARCHAR(50),view_emp_info.EMP_ID) +''+ ')' as [Employee Name],view_emp_info.emp_id,'' AS HOLIDAY ,'' as [LEAVE] ,'' AS 'ABSENT','Weekend'AS 'WEEKEND' from view_emp_info inner join tbl_org_weekend on view_emp_info.emp_id=tbl_org_weekend.emp_id or tbl_org_weekend.emp_id=0 where view_emp_info.BRANCH_NAME=@branch and days=datepart(weekday,@date) and is_weekend=1 and view_emp_info.emp_id not in (Select emp_id from tbl_emp_attn_log where tdate=@date) UNION select view_emp_info.emp_fullname+' '+'('+ ''+CONVERT(VARCHAR(50),view_emp_info.EMP_ID) +''+ ')' as [Employee Name], view_emp_info.emp_id,'' AS HOLIDAY, '' AS 'LEAVE','Absent' as 'ABSENT',''AS 'WEEKEND' from view_emp_info inner join tbl_emp_attn_log on view_emp_info.emp_id!=tbl_emp_attn_log.emp_id where view_emp_info.BRANCH_NAME=@branch and view_emp_info.emp_id not in (Select emp_id from tbl_emp_attn_log where tdate=@date) ) T1 where EMP_ID IN (SELECT EMP_ID FROM VIEW_EMP_INFO WHERE BRANCH_NAME=@BRANCH) )t2
