jquery $ .post Protezione CSRF

Come posso proteggere il seguente codice da CSRF?

$.post("lib/newEmployee.php",{employee_id: employee_id, employee_name: employee_name},
 function (output){
       //code                        
});

Ed ecco il mio modulo (è inviato dopo essere stato validato con jquery validate):

<form id="new-employee" class="inline-input" action="#" method="post"/>
     <div class="employee-container">
         <div class="field-box">
             <input type="text" class="input-block-level" id="employee_id" name="employee_id" autocomplete="off">
         </div>
         <div class="field-box">
             <input type="text" class="input-block-level" id="employee_name" name="employee_name" autocomplete="off">
         </div>
         <div class="field-box">
             <button type="submit" class="btn btn-success btn-block">New Employee></button>
         </div>
     </div>
</form>
