The man appears to have inadvertently clicked like on a tweet while dealing with a large influx of support messages (due to a promo going on) thanking Marriott for listing Tibet as its own country which was a huge no-no due to Mariott's presence in China. Execs fire him as a part of their "sorry China" grovelling.
My kneejerk is to believe fired man. I've clicked like on things by accident browsing regular Twitter, never mind a support system designed to skim through hundreds of requests. Unfortunately belief isn't going to restore the job, this is another lesson for the pile that companies will axe employees over fixing (heck, explaining) a problem with the system. It's the cheapest option.
If liking a tweet will infuriate the largest (by population) country in the world, maybe $14/hr support agents shouldn't be able to one-click like tweets.
Another question does occur - if it's such a big deal for them, why is/was Tibet listed as its own country in their system that prompted the liked tweet in the first place?
