Is a collective bargaining agreement binding on an employee who is a member of the union as well as on the employer?

There is not the slightest doubt, of course, that a collective bargaining agreement is ordinarily to be regarded as the union member's own voluntary act, and that the provisions of such a collective bargaining agreement are binding on an employee who is a member of the union as well as on the employer. The New Jersey and Pennsylvania cases all recognize the binding effect of a collective bargaining agreement between the employer and the employee inter se; and such is, of course, also the established law in California as respondent points out.
