The Union agrees during the existence of this Agreement, unless the Producer fails to comply with an arbitration award, not to strike against, picket or boycott the Producer for any reason whatsoever, and to order its members to perform their obligations to the Producer hereunder and to use its best efforts to get the employees to perform such obligations.
