Lecturers etc. may only participate in the NTEU industrial action if they are a member of the NTEU. Therefore you will need to consult with your lecturer etc. as to whether or not they are participating in the industrial action.
Tbh to me, it made more sense for the lecturers to email their students that their lecturer with them is cancelled, instead of asking all students to contact their lecturers to check if their lecture is running as normal tomorrow.
Also, I assume this strike doesn't effect tutorials??
