Lockout

An employer-initiated work stoppage where the employer temporarily shuts down operations or refuses to allow employees to work, used as a bargaining tool during labor disputes to pressure workers or their union into accepting the employer's terms.

What Is a Lockout?

Key Takeaways

  • A lockout is the employer's version of a strike: the employer shuts down operations and refuses to let employees work until the labor dispute is resolved on terms the employer finds acceptable.
  • Lockouts are legal in most countries when conducted as part of a legitimate bargaining dispute, though the specific rules and restrictions vary significantly by jurisdiction.
  • There are two main types: defensive lockouts (responding to a union strike threat or partial strike action) and offensive lockouts (employer initiates the shutdown to gain bargaining leverage).
  • Locked-out employees don't receive wages but may be eligible for unemployment benefits in some jurisdictions, depending on who initiated the work stoppage.
  • Lockouts have become an increasingly common employer tactic, particularly in professional sports, media, and manufacturing, as employers use them to control the timing and duration of work stoppages.

A lockout is what happens when the employer says: 'Nobody works until we reach a deal I can accept.' It's the mirror image of a strike. Where a strike involves workers walking out, a lockout involves the employer shutting the door. The employer closes the facility, sends everyone home, and stops paying wages until the union agrees to terms or the dispute is otherwise resolved. Why would an employer voluntarily stop its own operations? Control. A strike lets the union choose the timing: they pick the moment that causes maximum disruption (holiday season, peak production, a major product launch). A lockout takes that power away. The employer decides when the stoppage begins, which lets the company prepare, build inventory, line up contingency plans, and choose a time when the financial impact is minimized. Lockouts also demonstrate resolve. They signal to the union that the employer is willing to absorb short-term losses to achieve long-term labor cost goals. This changes the bargaining dynamic. Instead of the union pressuring the employer to make concessions, both sides are absorbing pain simultaneously.

Types of Lockouts

Not all lockouts serve the same purpose. The legal treatment and strategic implications depend on the type.

TypeDescriptionLegalityStrategic Purpose
Defensive lockoutEmployer locks out in response to a strike threat, intermittent strikes, or partial work stoppagesLegal in most jurisdictionsPrevents the union from controlling the timing and scope of the work stoppage
Offensive lockoutEmployer initiates the lockout during bargaining without a strike threat to gain leverageLegal in the US and many countries; restricted in somePressures the union to accept terms by cutting off worker income
Partial lockoutOnly some employees or work locations are locked outLegal in some jurisdictions; requires careful application to avoid discrimination chargesTargets specific bargaining units while maintaining some operations
Sympathetic lockoutEmployer locks out its employees in solidarity with another employer's disputeLegal status varies widely; often restrictedAmplifies employer-side pressure across an industry

Notable Lockouts in Recent History

Lockouts have shaped labor relations in several high-profile industries.

MLB lockout (2021-2022)

Major League Baseball owners locked out players on December 2, 2021, after the collective bargaining agreement expired. The lockout lasted 99 days, delayed spring training, and canceled the first week of regular-season games. The dispute centered on competitive balance (luxury tax thresholds), pre-arbitration bonus pool for young players, and revenue sharing. The resolved CBA included modest increases in the luxury tax threshold, a new $50 million pre-arbitration bonus pool, and a minimum salary increase. It was the first MLB work stoppage since the 1994-95 players' strike.

NHL lockout (2012-2013)

The NHL locked out its players for 113 days over revenue sharing. The league wanted to reduce the players' share of hockey-related revenue from 57% to 43%. The final deal settled at 50-50. The lockout shortened the season from 82 to 48 games and cost the league an estimated $1 billion in revenue. It was the third NHL lockout in 18 years, earning the league a reputation for contentious labor relations.

Kellogg's lockout/strike (2021)

Roughly 1,400 Kellogg's cereal plant workers went on strike for 77 days over a two-tier wage system where newer workers earned significantly less than veteran employees doing the same jobs. Kellogg's threatened to permanently replace all strikers. The resolution eliminated most two-tier provisions, included wage increases, and maintained premium healthcare benefits. The dispute drew national attention as part of the broader 'Striketober' movement.

Lockout Strategy for Employers

Employers don't lock out on impulse. A lockout requires extensive preparation.

  • Build inventory: Before locking out, manufacturers typically ramp up production to build enough finished goods inventory to supply customers during the work stoppage.
  • Secure replacement labor: Identify temporary staffing agencies, contract workers, or management personnel who can maintain critical operations during the lockout. In jurisdictions that allow replacements.
  • Communicate with customers: Warn major customers about potential disruptions and establish alternative supply arrangements to prevent them from switching to competitors permanently.
  • Legal review: Ensure the lockout complies with all applicable labor laws, including notice requirements, bargaining obligations, and restrictions on replacement workers.
  • Financial modeling: Calculate the daily cost of the lockout (lost revenue, customer impact, replacement labor costs) against the cost of the union's demands. The lockout only makes sense if the savings from a better deal outweigh the losses from the stoppage.
  • Media strategy: Lockouts attract public attention. Employers need a communications plan that explains their position without appearing to attack workers. Public sympathy tends to favor workers in labor disputes.

Impact of Lockouts on Employees

Workers caught in a lockout face many of the same challenges as strikers, with one key difference: they didn't choose to stop working.

Financial impact

Locked-out workers don't receive wages. Unlike a strike (where the union chose to withdraw labor), a lockout is imposed on workers. This distinction matters for unemployment benefit eligibility. In some US states, locked-out workers can collect unemployment benefits because they didn't voluntarily leave their jobs. In other states, any involvement in a labor dispute disqualifies both strikers and locked-out workers. Union strike funds may cover locked-out members, but the payments are typically modest.

Health insurance

Employer-provided health insurance during a lockout depends on the terms of the benefits plan and the employer's decision. Some employers maintain benefits during a lockout as a goodwill gesture. Others terminate coverage immediately, forcing workers onto COBRA or spouse's plans. In countries with public healthcare, this isn't a factor, which is one reason lockouts in countries like Canada and the UK carry less personal risk for workers.

Psychological effects

Lockouts create a particular kind of stress because the worker didn't choose to stop working. They wanted to keep showing up and earning a paycheck. The employer took that option away. Extended lockouts (weeks to months) create financial anxiety, family strain, and uncertainty about whether the job will still be there when it ends. Workers locked out of professional sports have described it as feeling punished for something they didn't do.

Lockout vs Strike: A Side-by-Side Comparison

Frequently Asked Questions

Is a lockout the same as a layoff?

No. A lockout is a temporary work stoppage during a labor dispute. The employment relationship continues, and workers are expected to return when the dispute is resolved. A layoff is a permanent or indefinite termination of employment due to business reasons (downsizing, restructuring, loss of revenue). Locked-out workers retain their employment status. Laid-off workers typically don't. The distinction matters for benefits, severance, and recall rights.

Can an employer lock out just some employees?

A partial lockout is possible in some jurisdictions but raises legal risks. In the US, a lockout must not discriminate based on union activity or protected status. Locking out only the most vocal union supporters while letting others work would likely be an unfair labor practice. However, locking out one bargaining unit while maintaining operations with non-unit employees is generally permissible.

How long can a lockout last?

There's no legal limit on lockout duration in most jurisdictions. A lockout continues until the dispute is resolved, one side capitulates, or an external authority (court, labor board, government) intervenes. The MLB lockout of 2021-2022 lasted 99 days. The NHL lockout of 2004-2005 lasted the entire season (310 days). Employer lockouts tend to last longer than strikes because the employer has typically prepared financially for the stoppage.

Do locked-out workers get unemployment benefits?

This varies by jurisdiction. In the US, it depends on state law. Some states (New York, California) allow locked-out workers to collect unemployment benefits on the theory that they didn't voluntarily stop working. Other states deny benefits to anyone involved in a labor dispute, regardless of who initiated the stoppage. In Canada, locked-out workers in most provinces qualify for Employment Insurance after a two-week waiting period.

Can an employer lock out workers and then hire permanent replacements?

In the US, the legal answer is nuanced. Employers can hire temporary replacements during a lockout. Hiring permanent replacements during a lockout is legally risky because it suggests the purpose of the lockout is to rid the workplace of union employees rather than to pursue legitimate bargaining goals. The NLRB has found this to be an unfair labor practice in several cases. The safer course for employers is to limit replacements to temporary workers during a lockout.
