Actually, they probably are, given the apparent glacial pace of change in the rail industry.Unless workers and unions are one and the same, I'd agree with that.
Frontline workers should always be fully engaged in systems implementations as they are subject matter experts with hands-on day-to-day operational knowledge and experience.
Unions are not railway operations subject matter experts.
Anyway, I've wasted too long on a thread I only opened to see what was going on.
