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

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?
