Teamsters v. Lucas Flour Co., , was a United States Supreme Court case in which the court held that a binding arbitration stipulation in a collective bargaining agreement constitutes a limited, implied no-strike clause over the matters subject to arbitration. Therefore, a strike to settle a dispute subject to mandatory arbitration was unprotected.
Significance.
Technically, this case was limited to an award of monetary damages to the employer for an unprotected strike. A later case, "Gateway Coal Co. v. Mine Workers", extended this principle to injunctive relief.
