Lightfoot has verbally committed to ensuring schools that need the services will have a nurse, librarians and more support staff. But so far, she hasn’t wanted to put staffing numbers into the union contract because it would tie her hands, and those of future mayors. They need flexibility. The number of students in the district has been shrinking rapidly. The availability of licensed nurses and teachers is tenuous. And there are high schools in CPS that have emptied out and are serving 50 students total. They don’t need a full-time nurse. Meanwhile, there are overcrowded Southwest Side schools that might need two. School officials and principals should be able to make those staffing and budgeting decisions, not the CTU.
