Reverting back to the original question, selection for a redundancy has to be made from a "pool" of eligible employees, using an objective method of selection (eg length of service, required skills etc). It is not laid down in law how you determine the appropriate pool: it could be eg one location or all locations OR one fleet or both fleets etc. The key is for the company to act , and to be seen to act, reasonably since otherwise they could end up with a hefty claim for unfair dismissal
