Oakland Unified School District spokesman Troy Flint says roughly 18 percent of the district's 2,000 teachers were absent, as compared to the 1-percent rate on a typical Wednesday.  Thousands of people joined anti-Wall Street protests throughout the city.
Several teachers' unions have expressed support for the Occupy Oakland movement, which made international headlines after an Iraq War veteran participating in the demonstrations was injured in last week's clashes between protesters and police.
Flint says the district got substitute teachers for most classrooms, and where that wasn't possible, children were sent to other classrooms.
This connects to what we are learning in class because this relates to the right to assemble and  There is no law that says they cannot for groups of people(assemble) in orderly manners.
This relates to something i have seen because i have heard many times about teachers petitioning, mostly because of pay cuts. My opinion is that it would be perfectly fine to assemble to protest. As citizens, they have that right and there would be nothing wrong with it. For example, a group of people protest about the signing of a bill saying that all people must go to a college. They would have the freedom assemble and protest.
