Hey Sam! I had the same kind of situation, just started a new job and didnt want to say I was going for a BA as don’t know the staff yet very well so didnt want any gossip or negativity going round. In the end I just told then I was going in for l a minor op on my back- so not really lying about the op, but just not the complete truth! 2 weeks off is a good idea, wish I’d booked more than 1 as sure il still be abit sore when I go back! With working in a pub aswell you won’t be able to lift anything for a good few weeks so youl need an excuse for why you suddenly can’t lift things ( that’s why I chose back op) lol xx
