Help with query (WHERE clause)

I have a select statement, but I think the WHERE clause is incorrect. This is my current code:

Select *  
FROM   Cases AS c
       LEFT JOIN Users e ON e.UserId = c.AlienId
LEFT JOIN dbo.Employment AS g ON g.UserId = c.AlienId
WHERE  c.Id = @caseid AND g.CurEmp = 1; 

Select allOpen in new window

In reality what I need is to get the g.CurEmp=1  inside the left join dbo.Employment

In other words, the left join should be to that table HERE CurEmp=1
and the final WHERE clause should only read c.Id = @caseid

How can I do this?
