UK also has Easter Monday as well as Good Friday. BTW, originally Good Friday and Christmas day were holidays here not by statute but in common law, having been observed since before records began.
Although banks are closed on bank holidays (though that's not true in all cases in Scotland), the holidays are not otherwise enforced. Most employers give them as paid days off (they may count them as part of your holiday allowance or not, but the number is adjusted accordingly so it makes no odds), but xx/7 jobs (e.g. broadcasting, many shops) may make no special allowance.
In the UK we have the curiosity that Easter Sunday is the one day in the year when shops over a certain size are forbidden by law to open - that's one of the very few direct effects of some people's religious observance that is enshrined in law here. That and restricted hours for the same shops (max six hours between 10am and 6pm) made up the compromise which enabled Sunday shopping to be allowed.
