Earl Warren,
National Labor Relations Board v…
“ The restriction on employees' concerted activities which would result from the construction placed upon § 8 (d) (4) by the Court of Appeals is obvious. [7] Too, we think it would discourage the development of long-term bargaining relationships. Unions would be wary of entering into long-term contracts with machinery for reopening them for modification from time to time, if they thought the right to strike would be denied them for the entire term of such a contract, though they imposed no such limitations on themselves. ”
