$(".submit").click(function(){
      var isChecked= $(".jobwork")[0].prop('checked');
      if (!isChecked) {
          alert("Please select atlease one jobwork");
          return false;

You have to check whether the checkboxes has a prop called checked in them. It is available only if the checkbox is checked.

 $(".submit").click(function(){ var checked = $(".jobwork").prop('checked'); if(!checked){ alert("Please select atlease one jobwork"); return false; }; }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="checkbox" class="jobwork" name="check"> <input type="checkbox" class="jobwork" name="check"> <input type="checkbox" class="jobwork" name="check"> <br> <input type="button" class="submit" value="submit">
