On one occaision in my life, I was hampered by belonging to a Union and was intimidated by Union members - the print unions in late 1970s.
On one occasion in my life, I was hampered by NOT belonging to a Union and found out too late they could have helped me - broadcasting in the early 1980s.
So I'm even handed about Unions, but many of these folks have never worked in any other line of work or employer or Union (yes there are many that HAVE) so it is not surprising that they have a narrow view. In the years to come, many will have the leisure to see what happened.
We are now in the end game of this dispute.
