Mayor Michael Bloomberg is now down to his final days as mayor for 12 years of NYC. But while he may be spending his final days touting his accomplishments de Blasio points out a rather disappointing mark the outgoing mayor is leaving behind.

According to New York Post, Bloomberg said that he considers his three terms of serving New Yorkers an "honor and privilege." He even pointed out in his four-minute address on 1010 WINS that he is more than grateful New Yorkers "took a chance" on a political neophyte amid the Sept. 11, 2001 attacks.

Additionally, in Bloombergs's final major speech last Wednesday, he boldly said, "New York City has never been stronger than it is today."

Nevertheless, according to a Time Warner Cable News report, Bill de Blasio would like to think otherwise. Although de Blasio recognizes Bloomberg's attempt to "cement his legacy," he singled out the outgoing mayor's negative legacy which primarily involves the expired contracts Bloomberg will be leaving every city union behind.

Then, there's also the question de Blasio's camp is not afraid to ask: did Bloomberg leave enough money to settle with the scores of unions?

But the still incumbent mayor believes that there's more than enough money, "as long as city workers give back like state colleagues did," Time Warner Cable News reported.

"The costs of today's benefits cannot be sustained for another generation, not without inflicting real harm on our citizens, on our children and our grandchildren," Bloomberg said adding that de Blasio could use his progressive credentials in convincing unions to give up retirement benefits.

However, it seems that de Blasio wouldn't be taking Bloomberg's advice as he admittedly prefers to look for savings such as in health care alongside his goal of bridging inequality.

"As much as I appreciate Mayor Bloomberg's advice, I would caution that one should be careful about giving advice from that perspective," de Blasio said.

Meanwhile, the billionaire Bloomberg is set to return to the private sector, but he is attending the New Year's Day inauguration of his successor, New York Post reported.
