Does adding a CSS class programatically via  add multiple if it already exists? IOW, with code like this:

1.   'change #date1Shift1JobLoc1Count': function(event) {
       var d1s1jl1Count = $('date1Shift1JobLoc1Count').val();
       if (d1s1jl1Count > 1) {
         $('date1Shift1Worker5').removeClass('hide');
       } else {
         $('date1Shift1Worker5').addClass('hide');
       }
     }

..if date1Shift1Worker5 already had the class 'hide' applied to it, would an additional 'hide' be added and, if so, is that a problem other than maxifying the CSS?
