Stoppage of work by employees (with picketing), often as members of a labor union, to obtain or resist change in wages, hours, or conditions. A “lockout” is a weapon of an employer to thwart or enforce such change by preventing employees from working. Another measure is “work to rule,” when production is virtually brought to a halt by strict observance of union rules.
Strikes may be “official” (union-authorized) or “wildcat” (undertaken spontaneously) and may be accompanied by a sit-in or work-in, the one being worker occupation of a factory and the other continuation of work in a plant the employer wishes to close. In a “sympathetic” strike, action is in support of other workers on strike elsewhere, possibly in a different industry. See also industrial relations.
