The Labour Relations Act defines these in the following terms:

“Strike” includes a cessation of work, a refusal to work or to continue to work by employees in combination or in concert or in accordance with a common understanding, or a slow-down or other concerted activity on the part of employees designed to restrict or limit output.

“Lockout” includes the closing of a place of employment, a suspension of work or a refusal by an employer to continue to employ a number of employees, with a view to compel or induce the employees, or to aid another employer to compel or induce that employer’s employees, to refrain from exercising any rights or privileges under this Act or to agree to provisions or changes in provisions respecting terms or conditions of employment or the rights, privileges or duties of the employer, an employers’ organization, the trade union, or the employees.
