You made small mistakes in client level and Interface level.Here is the correct code

var jsonData={ Name: name, Email: email, Phone: phone, Designation: designation, Department:    department, Fax: fax, Login_Id: loginid, Password: password };
$.ajax({
   type: "POST",
   contentType: "application/json; charset=utf-8", 
   url:"http://localhost/asd/Service1.svc/InsertEmployeeDetails",
   data: jsonData,
   dataType: "Json",            
   reloadAfterSubmit: true,
   success: function (msg) {
      jQuery("#list").jqGrid('addRowData'); 
   } 
  });
 }); 
});

Interface Code

[OperationContract]
[WebInvoke(Method = "POST",UriTemplate ="/InsertEmployeeDetails?emp_name={Name}&emp_email={Email}",RequestFormat =WebMessageFormat.Json,ResponseFormat = WebMessageFormat.Json)]
string InsertEmployeeDetails(EmployeeDetails empInfo);
