Here we go again... first, the top 124 have already had their opportunity to flow. Most bypassed but 14 flowed to NWA pre merger. Our top 124 have been at XJ for a very long time. Some in the neighborhood of 30 years. Our most senior was hired in 1981 and is 61 years old. The most junior of that top 124 that bypassed was hired in 1995 and is 47 years old. So if you were 60+ making over 100K getting everything you want, would you flow? Probably not. Everyone has their own reasons and believe it or not, do not find DL as the holy grail.
Of the next 108 who are eligible, very few will bypass. In fact only 7 have indicated they don't want to flow. A couple are "older" born in the 50s and the others I'm sure have their reasons. Several have either not indicated either way or are not eligible. This group makes up another senior bunch with 12-20 years seniority. The most senior eligible was hired in 1995 as well and the most junior eligible to flow was hired in 1998.
So obviously, the majority will flow. The ones that don't either can't or have personal reasons for not doing so. There's no reason to paint these guys as being stupid, lazy, incompetent or somehow moronic for not wanting to flow.
