San Francisco teachers are counting ballots after completing their second strike vote. If the vote passes — which union leaders say is likely — a teachers strike could be imminent. Before teachers can strike, they have to go through a few steps, including voting on the decision twice. Negotiations between the United Educators of San Francisco and the San Francisco Unified School District have been at an impasse over higher pay and better benefits. Two years ago, San Francisco teachers secured a raise of $9,000 with a five percent bump the following year.
