I Refuse to Train My New Boss—I’m Done Being Taken Advantage Of

I was told to train an intern. I spent six months walking him through everything I knew — every system, every client detail, every shortcut I’d picked up over five years.

Yesterday, they promoted him. He’s now my boss. Making twice my salary.

Everyone in the conference room looked at me, waiting to see how I’d react. I smiled and congratulated him.

The next day, everything changed.

I sent out a company-wide email that stopped people in their tracks:
“Effective immediately, I will no longer provide training, guidance, or support to management. My role does not include mentoring supervisors.”

Within an hour, HR called me in.

My new boss looked completely overwhelmed — he didn’t know how to handle half of his responsibilities without me. Management tried to pressure me, saying I was being unprofessional and damaging the team.

But here’s the reality.

I’ve been doing the work of two people for years. Covering mistakes. Staying late while everyone else clocked out. Taking on responsibilities that were never officially mine.

And for what?

To see someone I trained step into the position I should have had?

Now he keeps coming to my desk with questions, and every time, I direct him straight to HR.

The atmosphere is tense. You can feel it everywhere.

Some coworkers say I finally stood up for myself. Others think I’ve gone too far.

And honestly… I don’t know anymore.

Did I make the right call by drawing this boundary?

I’m exhausted from years of being taken advantage of. But now I’m starting to wonder if I’ve made things worse for myself.

I need real advice, because right now it feels like I’m barely keeping my head above water. I don’t know if I should keep standing my ground or try to repair the situation before it damages my career beyond repair.
