This will not happen, and the reason is that Obamacare made a great effort to decouple health care insurance and benefits from the employer. Since insurance is now available for purchase on the open marketplace, there are whole classes of employers who don't need to worry about including it in their benefits packages which they offer. It would be a step backwards to require or force companies to include it, especially to gig workers or contract employees; they should simply compensate them enough that they can afford to purchase an appropriate plan on the marketplace.
If you do not like this structure then you should have worked to block Obamacare from becoming law, because that was a primary objective of the legislation: to decouple health care plans from large companies and employers, and make that insurance more accessible, on the free market, to more workers than ever before.
