Loyalty from the 18-24 age-group is difficult to come by, regardless of which generation they belong to.
Now, the article fails to mention who the subjects of the study were betraying -- their Millennial peers, or non-Millennial ones? I would hazard to guess that most Millennials would happily betray their Boomer co-workers, perhaps even gleefully (schadenfreude?) -- and vice versa.
The question is open to interpretation even more -- Millennials count potentially everybody as a "workplace friend" (due to a far larger pool of competition), whereas Baby Boomers generally have only themselves as workplace friends.
The citizens of Leningrad in 1937 would surely not resort to cannibalism, but ask that question again in 1943...
These are two things which are not the fault of boomers.
Millennieals need to innovative out of their situation, change the game. Something like their own political party.
First, job-hopping millennials proved disloyal to employers, and now apparently they’re also disloyal to each other.
I would say, first employers proved disloyal to their employees . . .
The rest is just a rational response to a changing work environment and culture.
Suppose Al and Bob have been accepted to ycombinator. Things don't work out very well and 1 month out from demo day they're pretty sure they are going to bomb. Al gets a spectacular employment offer -- contingent on a start date before demo day. Bob doesn't. In fact, Bob has faith that they'll be able to make <metric of the year> if they try hard enough. Through no fault of Bob (and possibly no fault of Al), Al now has an incentive to throw Bob under the bus.
