This year I've had a Monday wedding, and two Thursday weddings.
Between the three weddings I've had to take 5 days annual leave (drove back after the Monday wedding to work the next day as it was the same week as one of the Thursday weddings and as I'd just got back from holiday I couldn't take the whole week off).
I have limited annual leave (just statutory), and whilst these are all people I dearly love and enjoyed the weddings (and would have been very upset not to attend), it's really screwed me over holiday wise and have meant I've had to a) take some unpaid leave to cover inset days etc and b) haven't been able to do any school trips etc.
I'm sure that none of the brides/grooms would have specifically thought about that as a consequence, but it is a shame that as the invitations came through my first thought was 'shit how am I going to manage this' rather than 'yay a wedding!'.
It is what it is, however when we got married we specifically chose a Saturday to make it as easy as possible for all our loved ones to attend without causing too much stress and issues.
I guess it comes to whether having the day/venue (that you wouldn't otherwise be able to afford) is more important than perhaps having a cheaper style wedding that focuses more on the guests (much of ours was homemade/family effort which was really enjoyable).
