Holding that union could not expel member because he filed unfair labor practice charge against it without first exhausting internal remedies as provided in union constitution
In Operating Engineers, we held that the union violated section 8(b)(1)(A) when it changed its hiring hall procedures to permit members to take six-day jobs without forfeiting list seniority by not informing a member who declined a six-day job in reliance on the prior five-day rule.
