No.
The Mackinac Center's tagline for this bill is misleading. This bill has nothing to do with "unfunded mandates."
What this bill actually wouild do -- according to the MC's own description and the text of the proposal -- is water down the recently enacted law prohibiting workplace smoking (including in restaurants and bars). That excellent law, which takes effect May 1 this year to protect the health and well-being of all Michigan citizens, was a lomng, long time coming. Efforts to negate it wholly or in part should be rejected.
