ANCHORAGE, Alaska — Alaska’s attorney general says a U.S. Supreme Court ruling requires members of state public employee unions to annually reaffirm or reject their membership.The Anchorage Daily News reported Tuesday that several state union officials believe the state will establish an annual opt-in system, while at least one says the move would result in a legal challenge.An Alaska AFL-CIO official says the announcement by state Attorney General Kevin Clarkson is the nation’s “most aggressive and interventionalist interpretation” of the 2018 ruling.Republican Gov. Mike Dunleavy’s office has declined to immediately say whether a yearly opt-in system will be established as a result of the ruling.The Alaska State Employees Association director believes the state will initiate an opt-in system and says “we will sue” if that occurs.___Information from: Anchorage Daily News, http://www.adn.comThe Associated Press
