What is the limitation on time limitations in a collective bargaining agreement?

In Britman v. Brody, supra (1952) 113 Cal.App.2d 642, 248 P.2d 932, cited by defendant in support of its contention that the [222 Cal.App.2d 384] plaintiff is barred from instituting any proceeding because he did not comply with the time limitations in the collective bargaining agreement, is easily distinguishable from the case at bar. In Breitman the time limitation was a bar to the institution of any proceeding; ² in the case at bar, as pointed out earlier, the time limitation only applies to the institution of arbitration proceedings.
