Of all the messages an Aussie man was presumably receiving on Facebook, he didn't get the vital one - you don't use the social media one to bag the boss.
The 28-year-old has recently lost an employment tribunal appeal after he was sacked for calling the company's pay manager useless and saying they would be "going down tomorrow".
He was fired when he showed up at work the next day, with the boss reportedly saying, "You can't work here - you made threats against us".
The employee said he had blocked the pay manager from seeing the post, but 11 other employees at the homeware retailer still read it.
A representative from Fair Work Australia said it didn't matter that the post was made on his home computer outside work hours as it still breached the company's employee regulations.
'Tweet' in dictionary
Want to know what the boss means when he tells you to crowdsource?
Or wondering if you should really take up your mate's offer of some parkour this weekend?
The Merriam-Webster dictionary now has the definitions of 150 new words, including "bromance", "cougar" and "tweet".
Social media is said to be behind the decision to include the whopping 150 words deemed to have become enough a part of American language to warrant a place in the dictionary.
The dictionary's editor at large was quoted as saying the words had "stabilised" enough to include them. Other words to get the nod were "helicopter parent" - which refers to someone who is too involved in their child's life - and "boomerang child", which is someone who keeps moving back home for financial reasons.
Editors are said to have devoted hours each day to monitoring what words people were using and how they were used by newspapers, magazines and books.
