Anyone who has ever had to use social media for work knows the fear of mixing up professional and private accounts.

You know, where you think you're tweeting from your personal Twitter account, but you're actually still logged on to your company's handle -- and then your boss is all like, "Why are we tweeting how much we hate tomatoes?", and you're like "Ahhhh!"

OK, so it's a completely 21st century problem, but it still happens and we'll admit that sometimes it keeps us up at night.

Luckily, we've never made that mix-up. Unfortunately, we can't say the same for Luke Welch.

You see, up until very recently, Luke was a "New Media / Press Assistant" for Sen. Susan Collins, the junior senator from Maine. On Wednesday, it seems that Luke meant to send out a personal tweet, criticizing Sen. Bernie Sanders. It read, "Good ol' @SenSanders is always entertaining. Not a huge fan. I'll give him this, the genetically modified food label makes sense." But, Luke didn't send it from his account ... he sent it out through Susan's official Twitter feed.

The errant tweet was only up for a minute or so before Luke took it down, he then personally tweeted a bunch of people to explain that it was his error.

When reporters reached out to Susan's office for more info on the story, the Senator's spokesperson released a statement explaining, "a junior staff person with access to Senator Collins' official account accidentally tweeted something that the Senator would never say and which does not reflect her views. Senator Collins' office has a zero tolerance policy for this type of activity. ... He has been let go."

Whoa. That's harsh.

Luke, we feel for you, buddy.
