                "processing": true,
                "serverSide": true,
                "order": [[ 0, "desc" ]],    //add this line
                "ajax":{
                    url :"employee-grid-data.php", // json datasource
                    type: "post",  // method  , by default get

                    error: function(){  // error handling
                        $(".employee-grid-error").html("");
                        $("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
                        $("#employee-grid_processing").css("display","none");

                    }
                }
            } );
        } );

    </script>

NB: Assuming your first column of table is some kind of auto incremented id

I think you should try this :-

$(document).ready(function(){
    $('#employee-grid').DataTable({
        "order": [[ 1, "desc" ]]
    });
});

You need to specify the default order column, like this:

var dataTable = $('#employee-grid').DataTable( {
        "order": [[ 1, "desc" ]],
 "processing": true,
                "serverSide": true,
        "ajax":{
            url :"employee-grid-data.php", // json datasource
            type: "post",  // method  , by default get

            error: function(){  // error handling
                $(".employee-grid-error").html("");
                $("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
                $("#employee-grid_processing").css("display","none");

            }
        }
    } );
