How to Get logged in user department in workflow

[RudhraKAM]

Can some one give me the code for getting the logged in user department 

I tried gs.getUser().getDepartmentID();  and getDepartmentID()  none of them worked 

[Johnny17]

    var interUser = gs.getUser().getID();

    var userRec = new GlideRecord('sys_user');

    userRec.get(interUser); 

    var result = userRec.department.getDisplayValue();

// If you want the object, you can skip the .getDisplayValue() at the end.
