I know of no lambasting of temps in the cabin. That is both mine and my wifes experience. The temps were a joy to have and they enjoyed themselves. They know how we operate an the current terms and conditions. Should BA ask them back on the same T&Cs then attrition may not be an issue. But to be asked to do the same job for less terms and conditions will be a different matter. Most of the temps in my wifes social circle are working. They are not sat at home awaiting a phone call. They will study the details of any new offer before considering a return. Alot of temps have worked for other airlines, and now all temps have had a true appreciation of the job. They know that it isn't all glamour. If they want to work to CAP 371 and different T&Cs then they may as well stay where they are. The incentive to work at BA was a higher salary and different T&Cs. Incentive gone. Holding pool depleting.
Of new recruits in the pool. They have no commitment to BA. They may be employed elsewhere. They have no idea of T&Cs nor salary because BA has not provided details. When the details come will they still be willing to give up what they have an join? That depends on those details, but what we can summise is that they will not be as currently offered.
