未签劳动合同赔偿计算方法及相关信息

根据相关法律规定，如果用人单位没有与员工签订劳动合同，则需要向员工支付双倍工资，具体计算方法如下：

赔偿金额 = 员工月工资 × 2 × 工作时间

其中，工作时间是指员工实际工作的时间，单位为月。

以下为计算未签劳动合同赔偿涉及的相关信息的获取方法：

1. 获取未签劳动合同的赔偿

    public function get_compensation($user_id) {
        global $db;
        $re_row = $this->get_resign_info($user_id);
        $compensation = 0;
        //获取最后一次的离职信息
        if ($re_row['have_contract'] == 0) {
            $compensation += $re_row['total_compensation'];
        }

        //获取交通补贴
        $traffic_sql = "select * from t_traffic_subsidy_info where user_id = $user_id and review_status=2 and is_deleted=0";
        $traffic_res = $db->get_all($traffic_sql);
        if (!empty($traffic_res)) {
            foreach ($traffic_res as $val) {
                $compensation += $val['compensation'];
            }
        }

        //住宿补贴
        $live_sql = "select * from t_live_subsidy_info where user_id = $user_id and review_status=2 and is_deleted=0";
        $live_res = $db->get_all($live_sql);
        if (!empty($live_res)) {
            foreach ($live_res as $val) {
                $compensation += $val['compensation'];
            }
        }

        $array[] = $compensation;
        $array[] = $re_row['total_compensation'] - $compensation;
        return $array;
    }

        $res_row = $db->get_row($sql_str);
        if (!empty($res_row)) {
            //获取最后一次发放的工资
            $end_time = $res_row['resign_time'];
            $sql_str = "select * from t_salary_send_log where user_id = $user_id and is_deleted = 0 and send_time <= '$end_time' order by send_time desc limit 1";
            $row = $db->get_row($sql_str);
            if (!empty($row)) {
                $row['base_salary'] = $row['base_salary'] - $row['total_deduct_money'];
                $row['total_salary'] = $row['total_salary'] - $row['total_deduct_money'];
            }

建议员工在未签劳动合同的情况下，保留好相关的证据，例如工资条、工作证明等，以便在维权时提供证据。
如果与用人单位协商不成，可以向劳动仲裁委员会申请仲裁。
