means A lockout is when an employer bars employees from the workplace to force concessions in a labor dispute, shutting down work from management's side rather than the workers walking off the job.

from A straightforward compound of 'lock' and 'out' — the physical image of bolting the doors so workers simply cannot get in. The word entered labor-dispute vocabulary in the 1800s as the deliberate mirror image of a strike: instead of workers withholding labor, the employer withholds the workplace itself.
