The union needs to have written proof of membership to be in compliance with the Janus decision. The union is telling teachers who have NOT signed the card that they are members in good standing. You do not need to sign to keep your job. If you have signed a card, you can still resign over the next few days.
Remember as the 7-day window comes to a close this weekend: the U.S. Supreme Court said in Janus that this is your choice. If you resign, you do not have to fund the union with fair-share fees or any other fees. But, again, you can voluntarily support your local without becoming a member. It is up to the local whether to accept your gracious gesture.
Minnesota teachers who are choosing to exercise their First Amendment rights and resign from union membership are being told they need to meet with their local union official before they can opt-out. This meeting is not required under the law, teacher contract, or under the union membership card.
