BANGOR, Maine — After months of waiting, City Councilor Joe Baldacci is pushing forward a plan to raise the minimum wage in Bangor and tie future wage changes to inflation.

Baldacci confirmed Tuesday the City Council will give his proposal a first reading July 13 and will hold a public hearing on the proposal July 15.

After that, the council could either take up the ordinance for consideration at its July 27 meeting or refer it to committee.

If approved, the ordinance would incrementally increase the minimum wage in Bangor, bumping the lowest paid workers to $8.25 per hour in 2016, $9 per hour in 2017, and $9.75 per hour in 2018.

After that, the minimum wage would fluctuate with the Consumer Price Index, a measure of inflation.

However, Baldacci’s proposal would not mean a pay increase for all minimum-wage workers. It would exclude anyone under the age of 18 as well as all tipped employees.

Baldacci said Tuesday it excluded teenaged workers because he was focused on adult workers who were trying to have independent lives and raise families.

Some city councilors have expressed concern about the proposal’s exclusion of tipped employees and those under the age of 18.

Baldacci said he would not object to the council including workers under the age of 18 if they see fit.

“It would be a friendly amendment if they want to include teenagers,” he said.

Baldacci said he chose not to include tipped employees because it would not be practical for the city to monitor whether their tips reached the new minimum wage. Employers must make up the difference if an employee’s reported tips do not equal the minimum wage.

“It’s just, on an administrative level, some unnecessary burden for the city to have to monitor tips, monitor that they are making enough on their tips to qualify,” he said.

Baldacci’s proposal comes amidst continued efforts to raise the minimum wage in Portland and after the rejection of a proposed statute from Gov. Paul LePage to prohibit cities from enacting their own minimum-wage ordinances.

Maine has not raised its statewide minimum wage since it went to $7.50 per hour in 2009, though the Maine People’s Alliance, a liberal-leaning policy group, has launched a campaign for a citizen-initiated referendum that could raise the minimum wage statewide to $12 per hour by 2020.

According to Todd Gabe, an economics professor at the University of Maine, raising the minimum wage from $7.50 to $8.25 per hour would impact 7 percent of workers in the Bangor metropolitan statistical area.

At $9 per hour, 12 percent of the workforce would be affected, and at $9.75 per hour, 18 percent would see an increase, he said.

Meanwhile, Baldacci rejected arguments against local minimum wage ordinances made on the basis that it would be too complicated for employers to handle different minimum wages in different cities.

“I don’t think that’s going to be a major issue. Employers deal with differentials all the time,” he said.

The ordinance would force the city to increase pay for some of its part-time seasonal temporary workers, costing the city between $50,000 and $60,000, Baldacci said.
