Is the notice of arbitration sent by SMS?

Legal analysis: there are written materials for filing a labor arbitration case and bringing a lawsuit to the court, that is, the notice of filing a case, and both filing and hearing are served by summons.

So if it's just a call or something, it's usually a trick of a liar. Please beware of being cheated.

Legal basis: Article 29 of the Labor Dispute Mediation and Arbitration Law. If the Labor Dispute Arbitration Committee considers that it meets the acceptance conditions within five days from the date of receiving the arbitration application, it shall accept it and notify the applicant; If it does not meet the acceptance conditions, it shall notify the applicant in writing that it will not be accepted and explain the reasons. If the labor dispute arbitration commission refuses to accept or fails to make a decision within the time limit, the applicant may bring a lawsuit to the people's court on the labor dispute.
