I’ve got it. This is brilliant by the way.
Phone up with a tummy bug complaint. Go to the interview and wow them as expected, come home with an offer of 50 grand p.a., a company car and a picture of your new boss who is a bit of a stunner who likes wearing nice lingerie under a pinstriped suit and getting to grips with new recruits.
Here’s the clever bit. On your return, dope the water cooler with some bacteria from your body (trust me, you produce lots of it), and wait for everyoe else to go off with a stomach bug thus convincing your manager that it’s just something that was going around.
