My question involves a background check in the State of: Michigan

I've been at my current job in healthcare for 8 years. I had a background check before hire. I was charged with retail fraud 16 years ago. I don't know if it was on my background check that they did or not. they hired me without saying anything about it. Now we have to get our fingerprints taken under Michigan Public Acts 27, 28 and 29. Do I have to worry about losing my job because of this past conviction 16 years ago?
