He hasn't received the mediation call yet. Will he call again?

If he doesn't receive the mediation call, he will call again. According to relevant public information, if the arbitration mediation call is not received, the arbitrator will call again. However, if you miss the call twice, you may need to take the initiative to contact the arbitrator or the arbitration commission to ensure that your arbitration case is handled. In addition, some arbitration committees will contact the parties through other forms, such as text messages and email reminders. Therefore, it is suggested that after receiving the notice from the Arbitration Commission, you should pay close attention to it in time and keep smooth communication to ensure that your arbitration case is properly handled.
