Which statement is true regarding one of the effects of expansion of public programs on employers?

Employers can reap the benefits of healthier, more productive workers without paying the up-front costs. Employees are not permitted to leave their employer’s plan and enroll in a public program. Coverage of the previously uninsured may cause labor costs to go up because health care costs in the entire system would increase. All employers are required to pay a “fair share” fee to help cover the costs of government coverage.
