I’m not sure what you’re talking about, exactly. I’ve worked union for the last 23 years (several years as an officer), and sat in on more than a few discussions about various policies, work rules, and all manner of procedures and practices, with both union officials and carrier officials present. Disciplinary hearings, on-property side agreements, etc. What union practices are you referring to?If you are an employer be careful what information you give out even concerning health insurance because it is against the law for an employer to tell the union employee anything concerning union practices.
