I publicly shamed an old manager on LinkedIn and Twitter, who now works at a Bank as an account manager that he was a complete asshat, miserable c**t, when I worked for him. He reported me, but my post is still there. A former employee of his retweeted.
Context:
20 years ago I was a new graduate working for a company building software. Worked 9-5, on 18K salary a year. I found out that the other grads got 26K, there were no skill differences, it turns out that I was the last guy in the recruitment campaign, so he thought he would lower the base salary. He got pissed off with me asking for a raise.
I didn't know about my rights back then, but he made me come in during evening and weekends to fix bugs. Unpaid, explaining that he didn't hire “bankers” whatever that means. I must have worked 12 hour days for 3 years. He skipped everyone's one-to-one, growth and development plans even though head office told him he needed to do it. We were graduates, we were on a programme to accelerate us to associate level. I had to keep my head down, did what he asked until I found an opening in another team.
I think everyone should go on social media and call out their old bosses if they were wronged.
