This theory seems entirely plausible. After all, people have often sued both corporations and government agencies over alleged unfairness in pre-employment testing procedures and have routinely won such cases. Therefore, it isn't at all unreasonable to entertain the notion that FedEx's number may have indeed finally come up in the judicial system. Another explanation for the policy change is that the economy played a part in FedEx's abrupt policy u-turn. FedEx isn't the only corporation that is experiencing such difficulties either.
Jobs are abundant just about everywhere in our current robust economy.
Also, when economic times are good and unemployment is as low as it is now, the pool of available labor shrinks dramatically. Corporations cannot be as particular as to who they hire when so many employers are fishing from a shrinking pool of available workers. It is almost universally accepted as truth among FedEx employees that our management remains indifferent to problems unless and until they can discern dollar signs associated with the problem. Until they can be shown a way to squeeze a buck out of somewhere, they'll usually remain indifferent to a problem regardless of the human ramifications it may entail. There's no doubt in my mind that one of the foremost reasons our former JKT policy was initially embraced by the company honchos was because it was such a slick way of screwing people out of propay as well as thinning out the ranks of older employees who might be nearing pension eligibility.
