Perhaps naive of me, but I thought my details would be handled confidentially by the HR department. Wrong! I've just received an e-mail from The Biatch's henchman, expressing their surprise at receiving my application and wishing me the best of luck in finding suitable employment elsewhere.
To which I have just fired off an e-mail in which I very politely reiterated my reasons for believing I would be an ideal candidate for any future vacancy, given that I know the company inside and out, know its products, its processes and procedures; have a proven track record of success within it (which they need only lift my file at HR for to verify) and have been trained up by the company, which means that if they force me to look for employment elsewhere, will be money down the drain as far as they're concerned; and ended by requesting they keep my application on file (and treat it with a little more respect next time -- though I didn't say it, it's there between the lines). And I bcc-ed the Board of Directors on it, as I'm sure they can't have forgotten me so soon.
But now the adrenaline is leaving my body, and the overriding feeling I'm left with is that of embarrassment.
