Company policy change, help needed

Hi All, new workplace policies coming into effect, these seem harsh and a little grey in the legality of it all. Are all these changes allowed? For context, the work from home policy was very flexible for as far as I can remember, most employees work from home 2 to 4 days a week. There was also no written requirement of advanced notice for AL. The mention of 9 hours a day feels a bit specific as well. Thanks in advance!
