You are forgetting about the clause that refers to major changes in the business. That little gem means they can do whatever they like that is in the "best interests" of the business. All they are required to do is "consult". It would be naive to think they won't use it. What has worried me over the years is the very small number of people who have read and understood the implications of clauses in both narrow and widebody EBAs. Too late to query them now.
