It's not unheard of. In one of my former lives, at a large bank, the on-call personnel used to be paid extra per time for each incident during nights and weekends. Some of them got sports cars, extended their house, built swimming pools... Until the on-call compensation scheme was changed.
From the moment those guys got paid extra just for being on-call but didn't get any additional compensation for solving problems, the number of incidents dropped dramatically.
