That's what I used to understand too. But my sister-in-law told her helper (She is my helper's sister) she will be off at easter because that's her labour holiday. Of course I told and showed to my helper it is not (gov't official website), then she seems not believe in me !!!!
I asked her to check with agency and her other friend. I asked if your friends used to have labour holiday off at easter, have you been ever invited out in the past years? IF that' holidays, most of your friends should go out for 3 happy days, right? Then she replied, "I don't remember.."
And she said but my sister-in-law said it is, then I go, "She can be wrong!"
