I think the article headline is spot on. The article itself goes on to elaborate and say, in different words, that "loyalty" has to be earned (by the company), and that a person leaving after X years (where X is less than some arbitrary amount that qualifies a person as "loyal") does not indicate "disloyalty". Your comment adds an additional subjective term, "reliability".
