I don't think so, I think it came about because it is COMMON PRACTICE for employers not to be allowed to give much information when called for references. It's company policy for lots of companies only to verify dates of employment and nothing else, because the companies do not want to have to defend against a lawsuit EVEN IF THEY WILL WIN. It's expensive and time consuming, so they just want to avoid the whole thing altogether.I think the myth is intentially perpetrated by employers to encourage employees to show their "true colors" during the dismissal process.
