This is not a valid interpretation of this case. The judge concluded that the employer fired the employee in retaliation for union activity. The company claimed they fired him for lying on his resume, but they couldn't prove that was the reason (which is their burden to prove), and it wasn't consistent with prior company behavior. E.g. they had a recorded conversation about how they could figure out a way to not hire a union applicant, and they had never fired anyone for a similar infraction before. Importantly, the only detail on the resume that was false was the name of the prior employer. They had accrued the same experience at a union employer instead. This case doesn't allow you to arbitrarily lie on your resume in order to salt, and you can still fire someone for lying if you can reasonably prove that.
