The opposite is also true. Should redundancies ocurr at any time in J*, then the MOU affords transfer to mainline to the reserved seniority positions.
Persons with a little more foresight sought these protections when the MOU was formulated years ago in profitable times to protect the interests of those in times like these.
You obviously have no idea what conditions would cause mainline management to trigger the clause in the said MOU.
As for a "separate organisation", your joking right?
