TIFU by giving my intern a “shape up or you’re out” talk… and finding out he’s our biggest client’s kid

I was new to a company. Our team got a new intern assigned to me. On paper he seemed fine. Smart school, decent LinkedIn, the usual. But his attitude was super casual.

I’d give him straightforward tasks. Clean up a comp sheet. Pull press releases and summarize key numbers. Fix formatting in a deck. But he would miss deadlines, send sloppy work, or disappear for half a day and pop back up with a vague excuse. Once he just didn’t show up for a morning call and later said he overslept. Meanwhile I’m covering for him, redoing his work, and looking incompetent by association.

After about a month of this, I hit my limit. I scheduled a serious one one. I kept it professional and firm. I told him the quality wasn’t acceptable, the reliability was a problem, and if it continued I’d recommend ending the internship early. He nodded, acted like he understood, said he’d do better.

Just that night my boss pings me to “hop on a quick call.” The quick call turned into me getting absolutely cooked. He was furious and said I was impatient, emotional, not “mentor material,” and that I made the work difficult. I was not the type of good cooperation. I was sitting there thinking: What??????

The next day the intern didn’t come in. And my boss still looked very angry. When I greeted him, he ignored me. I was so confused and frustrated. Later I was venting to a friend at another firm and I pulled up the intern’s LinkedIn like “look at this guy.” My friend went quiet for a second and goes, “Wait. That’s him.” I was confused and asked, "What? Who?" And I know this spoiled intern is the child of an industry exec. My friend said the kid interned at their company before and everyone basically handled him with oven mitts.

Suddenly the whole month made sense in the worst way. My boss wasn’t defending an intern’s performance. He was pleasing our client. I also felt bad that he didn't told me about the truth. Now I’m stuck doing damage control with a person who has zero reason to respect me, and I’m also trying to look “calm and coachable” while my brain is screaming. I genuinely thought I was managing performance. Turns out I was accidentally kicking a hornet’s nest with a client logo on it.

TL;DR: I didn’t know the intern I was mentoring was our big client’s kid. He had a bad attitude and missed deadlines, so I gave him a serious warning that we could end his internship early. He ghosted the next day, my boss ripped into me for being impatient, and I only found out later through a friend that the intern is an exec’s child and other offices basically babysat him.
