## Facts

- Two painters’ unions in Springfield represented the same craft and pursued lawful objectives under substantially similar constitutions and bylaws.
- Plaintiffs were painters who left the defendants’ union in 1897 and formed a separate local affiliated with a different national organization.
- In September 1898, defendants declared painters not affiliated with their national organization to be “non-union” and voted to notify employers.
- Defendants combined to compel plaintiffs to rejoin defendants’ union, seeking control over the local trade by subjecting all painters to defendants’ rules and discipline.
- Defendants’ agents visited employers where plaintiffs worked and demanded that employers induce plaintiffs to sign applications for reinstatement in defendants’ union.
- Defendants threatened employers with strikes and boycotts, including removal from a “fair list,” if employers continued to employ plaintiffs.
- Strikes were instituted to secure plaintiffs’ discharge when plaintiffs refused to apply for reinstatement.
- Employers feared business disruption and, in some instances, discharged or refused to hire plaintiffs as a result.
- Plaintiffs filed a bill in equity seeking to enjoin defendants’ concerted intimidation and coercion; the trial court entered a final decree for plaintiffs after a master’s report, and defendants appealed.

## Issues

1. Whether a combination by members of one labor union to force members of a rival union to join—by threatening employers with strikes and boycotts to procure the targeted workers’ discharge—is an unlawful conspiracy, even absent physical violence or property damage.
2. Whether equity may enjoin such conduct based on past injury and a likelihood of continued harm.

## Decision

- The Supreme Judicial Court affirmed the decree for plaintiffs, with a minor modification striking an overly broad and indefinite clause.
- The court held that defendants’ concerted plan to compel plaintiffs to join defendants’ union, implemented through threats of strikes and boycotts aimed at employers to obtain plaintiffs’ discharge or submission, was unlawful.
- The absence of personal violence or physical injury to property did not render the coercive combination lawful.
- Injunctive relief was proper because the conduct had caused injury and was likely to cause further injury.
- Holmes, C.J., dissented.

## Legal Principles

- Labor unions may have lawful purposes, but a concerted scheme becomes unlawful when it uses threats and intimidation to interfere with others’ right to work and to compel union membership.
- Coercion sufficient to support liability and equitable relief can consist of nonphysical compulsion; “restraint of the mind” may constitute coercion.
- A strike or boycott directed at third-party employers is unlawful when used primarily to force targeted workers to join a particular union rather than to obtain improved employment terms.
- Equity may enjoin an unlawful labor conspiracy where the conduct has produced harm and threatens continued injury, even without physical violence or property damage.

## Conclusion

The court treated defendants’ use of threatened and actual strikes and boycotts against employers to force rival union members to rejoin as an unlawful conspiracy and upheld injunctive relief to prevent continued interference with plaintiffs’ employment.
