Minneapolis school board member Josh Pauly said he has resigned, effective immediately.
Pauly's term as an at-large board member began in 2019 and was set to end in 2023. He was not planning to run for re-election, he said.
His decision comes amid the second week of a teachers strike that has closed Minneapolis Public Schools.
Union members have occasionally picketed outside the homes of school board members, calling on them to be more involved in negotiations and encourage them to join the picket lines.
Pauly said he decided to resign, in part, because trust between board members, the district and the community is broken.
"My doubts around district leadership are not new," Pauly said. "I don't feel like I am in a place where I can work towards rebuilding trust with the current MPS leadership."
Pauly was one of four board members who voted in October against renewing Superintendent Ed Graff's contract, which is still being negotiated and has not come back before the board.
Pauly said he first considered resigning after that vote.
