have (some/any) qualms about (something or someone)

 

I'm afraid, I don't quite agree.

I have qualms about it.

To have some or certain hesitations, apprehensions, uneasiness, or pangs of conscience (about something or someone). (Also often used in the negative to mean the opposite.)

I know it's wrong to feel this way, but I don't have any qualms about telling my boss I'm sick if it means I can have a long weekend.

I thought his promotion was a done deal, but it turns out the board of directors has some qualms about Jonathan.

Before we start, do you have any qualms about the plan we discussed?
