Great article Louise, thanks for sharing.  Interestingly, my sales support manager (21) requested last year to take a sabbatical for three months to travel and of course I agreed.   YOYO doesn't even apply here as at the other end of the spectrum I would equally have agreed.  She travelled to Thailand and this really was a fantastic experience for her, and of course it helps when working in the travel industry to be well travelled.  I think that allowing this flexibility brings about loyalty too.   It is more challenging for SME's to accommodate and cover the absence but I would still allow her and indeed encourage her to do it again.    BTW I have ticked off most of those on the bucket list, some even more than once!  The Northern Lights I was fortunate enough to visit last year and I'm my early fifties!
