Negotiations with police started in March.
"Everyone is watching to see what's happening with police, frankly," City Manager Jim Starbird said.
The proposed concessions are a key component of the city's plan to fill a projected $8.1-million budget shortfall without further cuts to city services. It is the third year City Hall has been forced to fill a significant budget gap amid increased costs and dwindling revenues.
Starbird has said that employee negotiations would likely continue past the June approval of the budget.
If the $3 million in savings doesn't come through, the City Council would be forced to reopen the budget and consider further cuts, which could potentially translate into layoffs or unpaid work furloughs for city employees.
Union representatives have said they are willing to talk about concessions, but only if they are absorbed across the board.
Jay Kreitz, president of the Glendale Management Assn., which is also set to negotiate a new contract effective July 1, said the union is open to helping the budget situation, but only if concessions are spread among all city employees.
His group was the only employee group to give up scheduled pay increases last year, he said. The Glendale Firefighters Assn. last year agreed to postpone two years' worth of scheduled pay increases, but is still set to receive a pay bump in July 2011.
"We are ready to do what the other associations are doing," Kreitz said. "We think it should be equal among employee associations. We have been very clear with the city that our members are ready to be part of a citywide employee solution."
On Tuesday, Glendale Police Sgt. Louis Haloulakos, president of the Glendale Police Officers Assn., said negotiations so far had been positive.
"We have some good dialogue going on right now, and we are continuing to talk," he said.
Regardless of police concessions, city officials will likely face a skeptical audience with the rank and file of the city's largest employee bargaining group, the Glendale City Employees' Assn., which must negotiate a new contract effective July 1.
Last year, the organization didn't approve its one-year contract until August, nearly a month after the group first voted down the original contract, which lacked a pay increase.
The union's president, Craig Hinckley, could not be reached for comment.
