From this year, the company I work for removed the cap on annual leave entitlement, meaning - theoretically - there is no fixed maximum number of days you can take. It is down to manager's discretion, so I could see that potentially causing some issues, but as a manager you would have to be able to justify refusing leave.
We already had a reasonable amount anyway (UK at least), although less than I had in my previous job. 25 days + a day for birthday, and a general 'wellbeing' day that was really just another day's leave, plus you could buy/sell up to 5 days. I always bought 5. During covid the company would give a fixed company-wide day off every 6-8 weeks and they've kept that going now post-covid, on a quarterly basis. They treat the work-life balance thing seriously.
This year with no limit I still took my usual two holiday 'chunks', one 2-week, one 3-week, plus Christmas week, but where the policy makes a huge amount of difference is the odd days that you might need/want here and there that you can now take without having to worry about eating into annual leave entitlement.
I could certainly see more large companies going this route, although it might be more difficult for smaller businesses to manage.
I can never understand people who get to the end of the year with loads of annual leave untaken.
I work for my holidays.
