Of course, it is natural for union officials to see themselves as benevolent godlike figures distributing goods to the plebes. But this particular plebe is doing just fine without you and would like to continue as long as possible without any unions.
And BTW guess what I found as looking up BT pensions on Google?
https://www.ft.com/content/5505d45e-ac29-11e6-ba7d-76378e4fe... BT has second-worst funded pension scheme in the world
Are you sure you've told the members of your union about that? Who would be left holding the bag when this thing blows up? Would it be you, or would it be those thousands of people who got unfunded pension promises? Or would it be UK taxpayers who would be forced to pay for it?
On one valuation the BTPS is in surpluss
Oh and I am an activist not a full timer ;-)
I'm sure these people were very happy with their union reps, and their union reps were very proud of it. Until it turned out their pensions are unfunded. And now the taxpayers have to pay their pensions.
