PHILADELPHIA (CBS) – For Mayor Nutter and the two non-uniformed city worker unions, the day after Nutter’s scuttled budget address saw only a slight cooling-down of the rhetoric.

It’s unlikely that any mayor was so roundly booed as Mayor Nutter was by the unions on Thursday. A day later Nutter said he didn’t take any of it personally.

“Haven’t thought much about it. That was yesterday. Can’t do anything about it. Got work to do today and tomorrow. That’s stuff that people do in public. Negotiations are not in public,” said Nutter.

For his part, District Council 33 Chief Pete Matthews said Nutter refuses to personally sit down at the table.

“This guy is the biggest fraud, plastic person I’ve ever seen. I’ve been saying it for years. Why won’t he challenge me on it? Because he knows it’s the truth,” said Matthews.

Stumbling blocks are pension reform and the mayor’s demand for the right to furlough.
