The TU movement has always suffered from people rising to office that have their own political agenda. When I was on UNISON regional committees it was dominated by the SWP. I was criticised for being a reformist many times. Block voting at conferences left me disillusioned. You have a mandate from your branch you could be casting thousands of votes but only the very interested will have bothered to go to that branch meeting to actually have their say. I know it’s down to the individual but it just wasn’t always a true reflection with such a small quorum.
Maybe it’s changed, any current trade union activists care to share how the in house system currently works is voting at conference like this still happening?
