overstress,
BASSA members don't seem bothered at all with their proposal. If you read CF you will see that most of the members are pleased with BASSA:s and UNITE:s proposal.
Some don't like the thought of losing another purser and a main crew has to do their job without being compensated. Many airlines have a working position as galley operator and they don't pay anything additional for that. The purser in CW is actually more or less working in the cabin as "main crew" and supported by the CSD during the meal service. I can't really see any difference there.
