My guess is Mike Bloomberg reluctant to call an emergency status and allow non-essential workers to stay home for 2 reasons.
1) It would cost the city a lot of money
2) My guess is SAIC CityTime would not be able to handle an emergency status since they haven't resolved massive bugs so this maybe yet another underlying reason Mike would do his best to not call for city workers that can to stay home!!
Anyway how will SAIC CityTime handle the over time with the departments they are responsible for last night and today?
My guess not very well!!!
