A snowstorm that caused hundreds of flight cancellations at O’Hare did not deter thirty-one District 141 activists from attending the first MNPL Seminar held for two days at the District offices this week. District 141 MNPL and Legislative Director Dave Roderick organized the event to educate and motivate members to get more involved in lobbying and political advocacy on behalf of Machinists Union members and all working people. US Representative Dan Lipinski from Illinois stopped by and addressed the participants.
