By my calculation, 92 pilots have left in approximately 14 months (by comparing seniority lists). In addition, there are 36 less pilots positions in the company due to the long list of changes, and with the announcement of the new 'Business Plan' there are likely to be quite a few less due to the disposal of the elite fleet
.
I would say that in most people's book that isn't too far off a mass exodus, and I think it will be even greater given the recent announcements.
