Have you ever added up all of the minutes that a typical on-air talent speaks? Does it add up to ten minutes a day?
If you're on a morning show, it's more than one person. That usually means there's a producer. So the producer oversees the digital.
Hopefully most of these people have degrees in communications. That to me involved more than front and back announcing songs. Anyone who has graduated college in the last ten years, social media and digital editing are part of the curriculum. "Digital" involves anything from doing a podcast, posting the creative bits from your morning show, posting links to articles that are relevant to the audience, articles that you might have referenced during your show, that sort of thing. Providing extra context to the on-air presentation.
I wasn't aware that air talent even qualified for bonuses. In my world, if you don't deliver ratings, why are you there?
