Explanation:

 Lockout is a work stoppage or denial of employment initiated by the management of a company during a labor dispute.[1] In contrast to a strike, in which employees refuse to work, a lockout is initiated by employers or industry owners. Lockouts are usually implemented by simply refusing to admit employees onto company premises, and may include changing locks or hiring security guards for the premises. Other implementations include a fine for showing up, or a simple refusal of clocking in on the time clock. For these reasons, lockouts are referred to as the antithesis of strikes.
