Also don't forget that BASSA came to the table with the 'temporary solutions to temporary problems' mantra.
All of the cost savings they devised were to be repaid back to the company after 2 years.
As the company had already agreed with most other departments a permanent change to T's & C's this was seen as both unfair and unworkable.
BASSA then point blank refused to negotiate on the basis of permanent change.
Look back through the BASSA newsletters and you will find all of the tantrums laid out there.
