DETROIT (AP) -- Michigan voters will have their say on several ballot issues related to collective bargaining, but none is more specifically tailored to a particular industry than Proposal 4.

The initiative would amend the state constitution to allow 42,000 home health workers to unionize, give them limited collective bargaining rights, offer training and create a statewide registry.

Supporters of the Keep Home Care a Safe Choice proposal on Tuesday's ballot say it will boost the quality of care for the disabled. Opponents counter the real purpose is to provide for collection of union dues from home health workers after GOP lawmakers outlawed that dues collection earlier this year.

The proposal would re-establish the Michigan Quality Home Care Council, which would be the so-called public employer of home health aides.
