Warren Mayor Mike O'Brien has been trying for the last year to deal with the city's financial problems and tight budgets.
In an effort to avoid further layoffs, he asked everyone to give up between 2 and 3 percent of their pay.
"My position is, and it will always be, that everyone in the city give concessions, that everyone help," he said. "We are all in this together from the mayor all the way to the operations department worker."
O'Brien, last month, wrote a check to the city for about 2 percent of his pay and made changes in his own health care plan. He said he wouldn't ask employees to do anything he wouldn't do.
City officials said all but a handful of workers have agreed to concessions.
Human Resource Director Gary Cicero said as of late Monday afternoon, the city's police chief, tax administrator and four employees of the auditor's office had not agreed to the concessions.
"We can just ask and of course we are hoping for 100 percent cooperation in the city," O'Brien said.
Police Chief Tim Bowers said he did not want to discuss the issue on camera, saying it was a private matter whether he gives the money back.
Bowers did say he took a $5,700 pay cut when he accepted the police chief's position. He said as a captain he received roll call pay and overtime, something he does not get as a chief.
The four employees of the auditor's office said they did agree to a wage freeze and changes in health care.
