It was the plan all along.
Many companies wanted Obamacare. Many want socialized medicine. Why? The cost for the company will be cheaper than having employer funded health care.
I wouldn't be so sure about that. In the long run, the overall quality of healthcare will suffer under Obamacare. It will take longer to get routine treatment; usual illnesses will be prolonged; perhaps the number of employee-hours to seek and receive treatment at all will increase.
In companies where employees can be easily replaced, this may not be a big issue. In companies that hire skilled professionals, they won't be able to be competitive, knowing that employee "healthcare time" out of office could significantly increase.
