The Hawaii State Teachers Association announced Friday that the union supports gay marriage.
The teachers union, which represents about 13,000 public school teachers, had opposed the 1998 constitutional amendment that gave the Legislature the power to define marriage as between a man and a woman.
On Labor Day, several other unions -- including Unite Here! Local 5 -- released a statement supporting marriage equality as part of the advocacy of Pride at Work Hawaii, an ALF-CIO effort.
State lawmakers will consider a gay marriage bill in special session in late October.
From the teachers union:
The current law provides that the Legislature reserves marriage for opposite sex couples, and while HSTA was instrumental in the effort in passing the legislation that allowed civil unions in Hawaii, it is now time to take the next step.
