Ace-Saginaw Paving Co. v. Operating Engineers Local 324

Plain English (For Everyone)

Imagine a union is upset with one company, so they picket that company's worksite. If that picketing also causes problems for another company that's just doing business there, that's usually okay under the law. This case says that as long as the union's main target is the company they have a dispute with, and they aren't trying to punish innocent bystanders, their actions are legal, even if it hurts other businesses.

For Legal Practitioners

The Sixth Circuit affirmed summary judgment for the union, holding that the employer failed to demonstrate that the union's picketing constituted unlawful secondary activity under Section 8(b)(4) of the NLRA. The court's analysis focused on whether the picketing was directed at the primary employer with whom the union had a dispute, distinguishing it from prohibited secondary pressure aimed at neutral employers. The rejection of tortious interference claims further underscores the narrow scope for employers to challenge union tactics that, while disruptive, remain within the bounds of primary labor disputes.

For Law Students

This case examines the distinction between lawful primary picketing and unlawful secondary picketing under the NLRA. The court applied the 'right to control' test and found the union's actions permissible because they were aimed at the primary employer, not neutral employers, to exert pressure related to the labor dispute. This reinforces the doctrine that unions can lawfully disrupt a primary employer's business, even if it impacts secondary employers, as long as the intent is not to coerce those secondary employers.

Scenario: You own a small business that provides catering services. You have a contract to provide food at a construction site where a union is picketing the general contractor due to a labor dispute. The union's picketing causes your employees to be unable to access the site, and you lose revenue.

Your Rights: You have the right to continue your business operations. However, if the union's picketing is directed at the primary employer (the general contractor) and not specifically aimed at disrupting your business as a neutral party, their actions are likely protected primary picketing, and you may not have a legal claim against the union for the lost revenue.

What To Do: Document the picketing and its impact on your business. Consult with a legal professional to understand if the union's actions exceed the scope of permissible primary picketing. If the picketing appears to be targeting your business directly or coercing you to pressure the primary employer, you may have grounds for a claim.

Is it legal for a union to picket a construction site if it disrupts my business, even though my business has no dispute with the union?

It depends. If the union has a labor dispute with one of the companies at the site (the primary employer) and is picketing that company, their actions are generally legal, even if it disrupts your business (a neutral employer). However, it is illegal if the union's primary goal is to pressure you, the neutral employer, to stop doing business with the primary employer or to force the primary employer to concede to the union's demands.

This ruling applies to the Sixth Circuit Court of Appeals, which covers Michigan, Ohio, Kentucky, and Tennessee. Similar principles are applied in other federal circuits, but specific interpretations may vary.

For Employers with multiple contractors on a site

This ruling provides clarity that unions can engage in picketing directed at a primary employer, even if it causes significant disruption to neutral employers operating at the same location. Employers should anticipate that labor disputes with one entity on a multi-employer site may lead to disruptions affecting all businesses present.

For Labor Unions

The decision reinforces the legality of primary picketing, allowing unions to exert pressure on employers with whom they have direct disputes. This affirms their ability to disrupt the primary employer's operations, even if secondary businesses are incidentally affected, as long as the intent remains focused on the primary dispute.
