A local group gets ready to fight back against those union protests like the "Shame On" banners and pickets you see around town.

The union protests are an issue Eyewitness News has been investigating for more than a year and we've now discovered a contractor's organization will file a complaint.

But meanwhile, the union was out again picketing at a heart clinic.

An organization representing 'non union' contractors says the union has gone too far. We'll show you what they plan to do and what happened here earlier Wednesday.

The marchers picketed in front of Comprehensive Cardiovascular charging workers on an office renovation are not paid prevailing wage. It's the latest type of action by a Carpenters' union local based in Los Angeles.

You've seen the 'shame on' banners. At the picket, I had a had time getting in. And we showed you patients being escorted in. Now a non union contractors' association says the union has gone too far.

The complaint is based on the situation at Santa Barbara College construction site where the project manager says he was roughed up by a union rep.

The Association of Builders and Contractors spokesman Kevin Korenthal says they'll file a complaint within a month.

This Union picket had its impacts too, office manager Teresa Blevins says for one patient. "The blood pressure was very high. He stated to us he felt threatened again by the picketers that were out there".

She says several of their elderly heart patients were upset by the noisy protest.

Police watched the protest the first day. Officers were called again by another patient. But what the union's doing 'is' within the law.

No one from the union would answer my questions. One man gave me an L.A. number to call because of the union action here.

And charges of Physical violence last month, the Contractor's group has a message to the union. "The union has gone too far, and they need to hopefully address some of the more negative aspects of what they're up to."

I called the spokesman in Los Angeles several times and called another union rep down there I've talked to before, but never heard back.

Again Police told me the picket here was within the law. As for the Santa Barbara College incident, the project manager promises to follow through on the police report he filed.

The non union group will file a complaint over that with the National Labor Relations Board.
