Hi, I had a professional paint all of the trim work and doors in my house. They used ProMar 200 Interior Waterbased Acrylic-Alkyd Semi Gloss. I questioned the painter about putting an acrylic over an oil base paint and he said it would be fine. That was around four weeks ago and the paint is scratching off. We are not living in the house so it has had plenty of time to cure.... Help how do I fix it?
Acrylic over Oil

No way to fix it short of removing the failed coating and starting over. If it's been a month and it's not bonded, it's not likely to.
In theory the newer acrylic/alkyds can bond directly to oil based paints. The catch that's often overlooked is complete deglossing is generally required to give the best results. If the prep work isn't done to very high standards, bond failures can easily occur.
Still, I would wait another week or so to make sure it's failed before proceeding if possible.

He should have scuff sanded and then applied a bonding primer. Woodwork is generally a hard surface and an old oil-based paint is very hard so latex paint has a tough time bonding to such a slick surface. Scrape, sand, do whatever it takes to get the paint off. Start over. Scuff sand, bonding primer, and 2 coats of semi-gloss latex.
Your painter screwed up, and if it's been four weeks, it's probably not going to get any better. There is no fix, as others have said, just doing it over: Remove the poorly-adhering paint, sand, prime, and re-paint. What a mess. I'm sorry...
This painter was obviously a professional, and he used the professional's choice for professional results. I mean, it has "pro" in the name, and it comes from the most trusted name in architectural coatings. 30% off, this week only!!!
