The Day Work Is Abolished

If we consider that an average of 2 bank holidays are added to the calendar every century and that there are roughly 300 working days left in our calendar today, then it makes sense to think that one day there won't be a single day left for work per year.
So, according to my newly discovered theory and my calculations on my HP-28S: in 150 centuries, that is 15.000 years, humanity will be freed from the torture of work and will be able to Burgerify itself. That certainly makes a case for environmentalists to carry on their efforts to save the planet until then.
