This proposal has been agreed, 15 votes in favour, none against, as @Sion posted in the Loomio thread:
Pleased to confirm the vote was unanimous to align CoTech as an industrial member group of workers.coop under the terms of the memorandum. As workers.coop has already approved the agreement, we can get going on practical steps.
We will start working on the practical steps next week at the gathering in Colchester, I hope to see lots of CoTech / workers.coop co-op workers there!
