In the UK, from my own experience, organisations, both business and charities are reducing employees work/life balance by having work-related events held at a pub, normally drinking after work. Some of these events can last hours and as far as I am concerned, staff are not even getting paid for them.
Many families are having partners who are working long hours and some parents and non parents alike, are going to after work drinks, and not just on Fridays but throughout the week too. All this adds up to a poor work/life balance.
It is good to have a celebration every now and then, but when it is work related, staff should be paid for it. Organisations need to recognise that staff have a home to go to as well.
