I mean they are allowed to do it. Is it annoying? Sure, but nothing says they can’t. Parents seem to think the world has to revolve around them and their needs and worry about them when changing policies. Businesses only care about theirs and don’t worry about your needs. Some want to get back to “normalcy” of pre-Covid, that’s their right. Would it be more helpful to say “at the start of 2023 we will be going x number of days in” instead of saying “next month you need to be in x number of days”? Of course, but that’s not how everyone chooses to operate.
