Nope, I'm not Donald Trump nor have I been fired, thankfully. I did, however, come across an interesting bit of English trivia today that I thought you might enjoy in today's turbulent economic times. You decide if this is true or not --
The history behind saying, "you're fired," actually stems from olden times when the only way for a settlement to get rid of somebody (short of killing them) was to burn their house down.
Well, even if it may not be true, you can use it at dinner tonight to impress your friends. My sympathies are with all the folks who have been laid off of late, but I'd say that is different than being fired. Incidentally, the only history I can find as to laid off is that it came about in 1955 as a euphemism for being temporarily unemployed.
