Police, firefighters and emergency medical personnel took their displeasure with contracts imposed on them by Mayor Dave Bing to his doorstep.
The Detroit News reports http://bit.ly/Qmv44G that more than 100 city workers and their families rallied Friday outside the Manoogian Mansion, the mayor's official residence.
They protested a 10-percent pay cut, layoffs, demotions and work rule changes.
Detroit Police Officers Association board member Clive Stewart said police "understand that there has to be sacrifices" but will not stand for "eroding away" of their contract and "union-busting tactics."
Bing imposed the contracts last month without negotiations. Salaries will be cut by 10 percent and employees must come up with 20 percent of their medical costs.
Bing said the cuts will save the city more than $100 million a year.
