Sounds like a wind up to me. Whilst it is true that the employer holds most of the cards with this draconian legislation(until the zealots get banished to opposition) there was an amendment that Barnaby and pals had added to the legislation.
Namely I recall there was an additional protection with respect to an additional EBA's protection before the unilateral termination of terms and conditions some 90 days after expiration. The EBA signed after (I think) March 2006 was the last..
So unless there was an engineer EBA post Work"choices" that has expired I think there will only be a redundancy if compensation is paid, and none of these bull**** "operational reasons" to avoid obligations.
Collective Bargaining is our strength, be us pilots, engineers or groundstaff.
I am not affiliated with any union, I will however never vote Conservative again...
