Probably why I didn't use the term.
Other than that, if I were an employer, I would at least want someone who can do the job at hand of filling out a form because some mistakes can be costly to the employer and the employer would not always be there to look after these mistakes. As for job training, that part is understandable if it takes a while for an employee to get it. But again, there comes a point when an employer will just say that the person is not fit for the job.
The role of these things are to sniff out candidates for the job at hand.
I've definitely seen what you're talking about but to be honest by the time peoples fitness is in question they've climbed the ranks and are bosses of some description and well able to argue that it is not them but their junior or subordinate officers which are culpable for the decisions, prevailing practice and culture which has been created by stupid and self-serving decisions.
