From an Associated Press story based in Miami:

Teachers call it the "yo-yo effect." School budgets, facing severe reductions in state funding, are cut and layoffs are made, but then some or even all of the teachers are hired back over the summer as officials scramble for money.

This year, many teachers and other public employees are anxiously waiting to see if a pending $26 billion stimulus bill — which passed in the Senate this week — keeps them out of the unemployment line.
