Ohio Public Radio's Andy Chow reports.
The so-called "Raise The Wage" amendment would increase the minimum wage by annual increments to eventually reach $13 an hour by 2025.
The group trying to put the measure on the November ballot got the go-ahead from the Ohio Ballot Board to collect signatures.
Supporters of the plan would have to gather nearly 443,000 valid signatures by the beginning of July in order to qualify for the ballot.
The proposed amendment resembles similar measures passed in state legislatures around the country. Democrats have proposed bills to raise the minimum wage several times in the last few legislative sessions, including one that would hike it to $15 eventually. None have moved very far – though a law to stop local communities from increasing the required minimum wage passed in 2016.
