It’s not just the city schools that are closed to new hires now. Because of the State Senate’s failure to approve a city tax hike, Mayor Bloomberg has frozen hiring for the entire city starting today. 

Among the people who are not being added to the city’s payroll are 150 school crossing guards and 175 school safety agents who were set to start walking the halls this fall. (There are more than 5,000 safety agents in the school system, and some advocates have said that’s too many.)
