Illinois Law dean and professor Vikram Amar joined Illinois Public Media's The 21st to discuss Supreme Court case Janus v. AFSCME on February 27th. The case actually began here in Illinois and challenges "fair share fees." The term refers to fees that workers are required to pay, regardless of whether or not they want to join the union, to fund union activities such as wage negotiations, work hours, and health care.

Amar spoke about how the First Amendment comes into play, whether or not it is possible for the justices to separate politics from the law in this case, and much more.

"Labor law has always been thought to be a domain that involves regulation of workplace conduct that is exempt from the First Amendment. And if you pull on this string, as the majority of the Supreme Court seems to want to do, a lot could unravel," he said.
