As janitors marched in the drizzle through Warner Center, chanting slogans for higher wages, LAPD Officer Ray Sua hovered in the background, poised to quell any violent outbreak or temper flare-ups.
As is typical these days, nothing happened: Another loud but peaceful labor protest came to an end.
Sua will be back on the protest beat today, monitoring the janitors as they march along Ventura Boulevard in Encino demanding bigger salaries and paid sick days.
Every week across Los Angeles, officers with the LAPD's 11-member Labor Relations Section monitor picket lines, rallies and marches in an effort to balance rights to free speech, assembly and public access with those of property owners.
The unit also tries to prevent conflicts between uniformed police and labor at a time when more unions are using boisterous street theater and civil disobedience tactics.
Officers communicate with unions, asking how they can help organize traffic and safety during union actions, said David Stilwell, the Southern California director for Service Employees International Union, Local 1877, which represents janitors.
"The labor community out there doesn't move without notifying us--not because they have to, but because they trust us," said Lt. Charles Helm, who heads the labor detail.
Union leaders say that they would rather work with the labor detail than with patrol officers who are not as well-versed in union rights and who tend to side with management when responding to a confrontation.
"We're not anybody's agent," Helm said. "Our whole role is to be objective. We have the expertise to balance the penal code and the 1st Amendment."
The relationship between law enforcement and labor, however, is rooted in a contentious past. Problems came to a head in 1990 during a janitors' protest in Century City.
At the time, more than 300 striking janitors and their supporters refused a surprise police order to disperse. Riot-helmeted officers attempted to drive them back with clubs; 16 people were arrested, 40 injured.
Police said they decided to halt the march because they had received intelligence reports that the protesters planned to dump trash at the Century City office towers and to disrupt traffic.
"That whole fiasco could've been averted if police had used the labor detail guys," said David Sickler, the southern regional director for the California Building and Construction Trades Council. Sickler marched with the janitors back in 1990 and was jabbed in the back by an officer's baton, he said.
