The Association objected to a Review Officer's decision not to order the City to increase the pay equity adjustment for the Communication Operator job class.
The parties had negotiated a Pay Equity Plan which was approved by City Council, but the City subsequently refused to execute it, arguing that the Plan's provision for an hourly wage adjustment did not reflect the parties' intention to equalize annual salaries (a 'mutual mistake').
The Tribunal held that the Plan was binding on the City, as it had been properly ratified by Council.
The Tribunal rejected the application of the equitable doctrine of mutual mistake in the labour relations context, finding that parties are bound by the objective meaning of their written agreements.
The City was ordered to pay the hourly adjustments specified in the Plan, with interest on unpaid amounts.
