5-2 We all know that employers check out the social media accounts of potential candidates， but did you know that they also look at staff accounts? Three months ago， I had just started a job in a restaurant. The first Saturday I worked there we had a staff shortage as quite a few people were off ill. At lunch time， I was left to serve about 20 customers by myself! As you can imagine， service was slow， and a few customers were quite rude to me. By the end of the day， I had a terrible headache， sore feet and was in a very bad mood. I just wanted to let off some steam， so I went home and wrote a blog post about the terrible day I＇d had. It was supposed to be funny， but I did bad-mouth some of the customers， especially a large woman wearing a purple coat who had shouted at me because her coffee was cold. Then I shared the blog post to my social media accounts. That was a big mistake. I had forgotten that I was friends with my boss on social media. Unfortunately for me， the woman in the purple coat who I had described in my blog post turned out to be his wife! I was called into my boss’ office and fired the next day. What did I learn from this? Never write anything negative about your work on social media: it will always come back to bite you. 48. Why was there a staff shortage?
