Nat'l Labor Relations Bd. v. Milk Drivers & Dairy Employees, Local 338

In Milk Drivers, an 8(a)(3) violation was established where it was found that by becoming a "good" union member, see Radio Officers' Union, supra, 347 U.S. at 40, 74 S.Ct. at 335, an individual had the opportunity to become a shop steward and thus obtain super-seniority.
