You never know when your past is gonna come back to haunt you….

And that’s especially true when it comes to trying to find a new job!

So remember friends, be nice and polite to all your co-workers…because you might need them later down the line when you least expect it.

Read on to see what happened in this story from Reddit!

Condescending colleague – I cost him his desired job.

“I work in admin in a private school.

Some years ago we had a new history teacher – straight out of university – who thought he was the Universe’s gift to education, and because I worked in admin, I was a lower form of life.

Yuck…

He was condescending and quite often just plain rude.

A few years later, he had moved schools.

My boss was out of the office, so I picked up a call for him, and was asked if he could give a reference for a former teacher, who had applied to one of our city’s most prestigious boys’ schools.

I asked who the reference was for, so I could give my boss a heads-up, and – oh joy!

It was the unpleasant ex-colleague!

Before I could stop myself I started to laugh.

The very nice deputy head on the line asked me why.

Well…

I told him I was prejudiced, because of the way he treated me, but also said that the history marks the years he taught at our school were the worst they had ever been.

My boss came back later and phoned this man, and when asked if he would re-employ said person, said definitely not.

Boss and I shared a good laugh about that one!”
