CTC probably has a high proportion of non-members. The union-only briefing I attended probably lost about a third of those attending the open session. If you look at the early posts in the natsnet pensions area, you will see a lot of complaints about ineligibility to vote. Legally, the non-members' involvement ends with the 'consultation'. The bulk of the members will be Prospect ATSS and PCS. Both may have a different view to the ATCO's branch because they see more of the company than just the Ops Rooms.
