The complainant alleged that the union breached its duty of fair representation under section 68 of the Act.
The union and employer had agreed that an error was made in interpreting the collective agreement regarding a job posting during a layoff, resulting in the complainant losing her position and returning to the status quo.
The Board found that the union acted reasonably to correct a mistaken interpretation of the collective agreement and did not act arbitrarily, discriminatorily, or in bad faith.
The complaint was dismissed.
