The employer brought a preliminary motion objecting to the Board's jurisdiction on the basis that the union's referral to arbitration was untimely.
The union conceded the referral was late but argued the employer waived its right to object.
The Board found that the employer failed to raise the timeliness objection regarding the referral for approximately one year, during which time it engaged in discussions about the merits, sought particulars, and scheduled arbitration dates.
The Board concluded these actions constituted a 'fresh step', thereby waiving the employer's right to rely on the time limits.
The employer's motion was dismissed and the grievance was ruled arbitrable.
