NYC is prepping for massive teacher layoffs this summer.
Teachers union layoff rules are first-in, first-out.
This means all new NYC teachers that have been hired in the past three years are going to get the boot REGARDLESS OF PERFORMANCE.
Even the liberal parents in NYC are upset at the first-in, first-out union layoff policy.
I think you mean LIFO - Last In First out. First In First out (FIFO) would mean that the older teachers would leave first since they were the first ones in. Think of a bank line (or queue) being FIFO. A stack of plates (or Teachers in this case ;-)) would be LIFO.
