Given the average age profile of AB users, I doubt that there will be many people here who'd normally be working on June 2nd anyway.
i suspect that some people who've been given the day off by their employers though might not actually want it. If an employee's contract states "28 days holiday per year, inclusive of public holidays" he or she would normally have 8 'fixed' holidays and 20 days to play with in agreement with the employer. If an extra public holiday is given, he/she will end up with 9 'fixed' days and only 19 'flexible' ones, which might result in the messing up his/her usual holiday plans!
