If you’ve ever resigned from a job, you know it’s typically a formal affair.

You generally draft and send a professional letter to your boss or HR informing them of your choice.

When it was time for Sam Baines, 22, to leave his work, he wanted to do stuff a little differently.

By sending a sympathy card to his boss, he resigned in an unconventional way.

Baines told INSIDER he had to leave his job at a call center in Sheffield, UK because in the fall he would go back to college. He had been working there for nearly a year, but it was time to move on.

“We are a really close team and have a fantastic manager, so we’re always joking around and having fun,” he said. “I knew I had to do something a little more creative when giving my notice to try and get one more joke in before I left!”

Baines said he came up with the idea because he was always joking with his team about how much they’d miss him when he left.

“It went down great and helped make a positive from an otherwise sad situation.”

His soon-to-be former coworker, Hannah, shared an image of the card on Twitter and it went viral.

The front of the card reads, “So very sorry for your loss,” while the inside reads, “Thinking of you at this difficult time.”

Sam penned a note of his own inside, let his boss know that his last day would be July 28.

“Everyone was laughing and pretty amused with the card,” Hannah told INSIDER. “It was done in good spirit and not as a petty reaction as some people think.”
