There's a bunch of obvious problems, off the top of my head: People should be able to to look for a job without necessarily tipping of their current employer. Ambition and hard work, unless expressed very carefully, could well become an endless trap. Those who work in industries with terrible unemployment will continue to be stigmatized even after they abandon their search in their old field and strike out into new ones. There's potential for abuse, e.g. Apple could falsely report all its current employees as submitting bajillions of resumes and thus prevent them finding other jobs. There's the problem of recruiters who submit resumes indiscriminately on a job seeker's behalf, sometimes without permission or even the seeker's knowledge.
