Can she do that?

We knew no good would come from our new boss. Today we were informed by email that we may not enter the staff lounge without prior permission. The STAFF LOUNGE. No entry for any reason without asking. We are not toddlers. And our staff lounge has always doubled as a work space. A place where we made posters and decorations for special programs. We explained this to Comfort Inn. She does not care. She says these things do not need to be done. They are to be done at the main desk or not at all. We are not to be away from the main desk without express permission from her. This seems problematic.
