We all want to be the best at our job, to never make a mistake, and to never feel like we have to be on our toes when we step into the office. We also all know that it is practically impossible to feel that way, because everyone makes mistakes, especially during the 8 hours we are on the clock.

That being said, there are different degrees to our mistakes, right? Some mistakes our small and insignificant, like calling your coworker by the wrong name, while other mistakes can easily lead to you being fired, like accidentally locking a customer in the building overnight. We can do our best to avoid making big mistakes, but if we can't help it, at least you can be comforted by the possibility of laughing about said mistake in years to come.

That is exactly what is happening below. A viral TikTok in which people were asked to share the biggest mistakes they made on the job led to the funniest comment section ever. Employees had a lot of life-altering mistakes to share with the world, and the rest of us got to have a good laugh at their expense.

Keep scrolling to read some of the biggest (and funniest) mistakes employees made that forever changed their careers…
