The details of the ballot seem to me to be a side-show to the real issue.
Thousands of staff have voted for a strike, and between half and two thirds of them will strike.
When will the responsible local BA management get out and about to talk to, to influence and to persuade staff to change their minds?.
Sitting in an office is a cop out. Waiting to be approached is a cop-out. Get on the planes, get on the phones, go and have conversations!!!
If each manager has 200 to 300 staff to oversee, 80 could easily be spoken to each and every week, 30 minutes each..
As for the CSDs that support the strike, they are supposed to be first line managers, not strike leaders. They must be performance managed out of the organisation.
