Unfair labour practice complaints dismissed due to excessive delay and prejudice to established bargaining relationships.
The Carpenters' union filed unfair labour practice complaints against the Labourers' union and various employers, challenging subcontracting clauses in residential framing collective agreements.
The respondents moved to dismiss the complaints due to delay and abuse of process.
The Ontario Labour Relations Board found that the Carpenters had delayed excessively in prosecuting the complaints, causing substantial prejudice to the respondents and striking at the heart of established bargaining relationships.
The Board exercised its discretion under section 89(4) of the Labour Relations Act to decline to inquire into the complaints and dismissed them.
