That’s How You Delegate!

Senior staffers should always be clear on when to ignore stuff:

One of Hizzoner’s top aides was sounding alarms about the fraud-ridden payroll system more than four years ago, The Post has learned, and the response from City Hall was silence.

The warnings came from Paul Cosgrave, the mayor’s commissioner of information technology and telecommunications at the time, according to three people with direct knowledge of the discussions. And Cosgrave brought his concerns directly to Bloomberg’s senior staffers — who are supposed to have Hizzoner’s ear.
