Quest may not need them in Eugene, if the testing they were doing is being done in Portland or Seattle. I'm guessing the only lab work remaining at the Riverbend Annex will be that which supports the hospital directly- the 'stat' labs. That leaves the techs with the grim choices of retiring, moving, or hoping they can get hired on at the stat lab- whatever that looks like, and knowing that they will be competing against their former coworkers for the few positions. 

As they say, "may the odds be ever in your favor!"
