GPL should apply to anyone legally being given a copy, as the giver may be required to sublicence it under the GPL in order to be permitted to distribute that copy. If you simply 'find' a copy, GPL doesn't necessarily apply. And employees in most circumstances are not legally 'given a copy' - just as if the employer hands them a wrench to work with, that doesn't become the employee's wrench, and that applies to all kinds of copyright issues, any prohibitions to sublicensing don't prevent the product being used by employees because it's never licensed to them, etc.
