Bubblehead,
I do not believe you are missing anything. Mgmt vacations are very different --the first day worked in the year makes you eligible for all vacation time earned per years of service.
In other words if I was 55 yrs old with 30 yrs of service and my birthday was in the fourth Q --I would work one day in Jan and receive 6 additional weeks of vacation --right or wrong. Also people hold on for there last mip in the 4th q and certain levels also recieve an additional stock option when the New Year starts.
It would make sense for UPS to have all of these people commit during the first two months of the year --the highest number of mgmt people leaving before offering any other enticements to those thinking about hanging on for another yr or two.
My personal opinion is that there will be no buyout --time will tell.
