My office does an extra public holiday elsewhere in the year, and only get one day off at Easter. It's supposed to be Good Friday, but I'm working today taking Monday off instead. The advantage of this is that the office is pretty quiet - there's only five of us in. To celebrate, I'm planning to make mojitos at Mojito O'clock for those who want them. We normally do Beer O'Clock on a Friday afternoon, but making mojitos seemed like a far more sensible course of action.
I now work in the food manufacturing and we don't officially get bank holidays off. We don't have to take them and can use the holidays elsewhere, which is useful. I would have liked today off but since the factory is producing it was insisted I was in and I'm doing very little since all my suppliers are off today so it's not like I can fix any issues anyway. They nearly forced the factory to produce on Monday meaning the shop floor staff would have only had Sunday off.... There was rumour of a strike so they quickly rearranged the plan.
I don't even think they're unionised. More like them thinking "fuck working all Easter" - they're majority Polish and fairly religious so I don't blame them for actually wanting some time off rather than working constantly.
