Do any employers actually provide that information? The most I've ever had any previous employer ever say about my time there is, "Eric worked here from $start_date to $end_date." I understand there to be liability involved if they say anything more.
Past employers can say whatever they want. They open themselves up to legal liability in doing so, though, with basically no value to themselves. Theoretically as long as they're telling the truth, there is no legal liability. In reality it's more nuanced. e.g. An employer who reveals that a former employee was absent a lot might be sued successfully if the absence was within the company's sick day policy, or the reason was a disability.
Saying nothing is the safest choice. Most employers only confirm employment as a courtesy to their former employees.
Not sure what you mean. Employers would prefer to give no information about previous employees, specifically "to cover their arse from lawsuits". They confirm employment dates as a courtesy because it can be difficult to get a job without confirmation of previous employment.
Tangentially, it's really abrasive and generally unnecessary to start a comment by calling someone a liar. You can disagree with me here, and that's totally fine. To call me a liar for holding a different opinion than you makes you seem really petty. Arguing about the reason companies will disclose employment history doesn't seem to be the time to break out this sort of accusation.
