It can be difficult to get a permanent job but aside from worrying about your financial condition, you also need to think about those dreadful interviews you have to go through.

In most cases, you’d have no idea whether you impressed the employer or not and you just need to patiently wait to get that call.

One executive manager wrote an article and claimed she had one simple rule when it comes to employing people.

Jessica Liebman took to Twitter and shared her article: “Hey, I wrote something! … I’ve been hiring people for 10 years, and I still swear by a simple rule: If someone doesn’t send a thank you email, don’t hire them.” She also added a link to her article posted on Business Insider.

In her article, she said: “As a hiring manager, you should always expect a thank-you email, and you should never make an offer to someone who neglected to send one.”

Her post started a long debate online on whether or not it is okay to judge someone based only on their knowledge of unwritten rules and social skills.

Melissa Hope tweeted: “It’s professional courtesy to send a thank you email. Plenty of people with talent out there who still have manners.”

Most people were furious. They tweeted:
