You dont understand what 'legal duty of care' means and how its different and not different to university pastoral support.
Definition: A duty of care exists when it could reasonably be expected that a person's actions, or failure to act, might cause injury to another person.
In a university context it means knowing what universities' responsibilities are to its students, and vice versa, and ensuring there are consistent policies and support systems in place across the sector.
For example, if a student is having a mental health crisis and the University knows they plan to take their own life, and the student has given consent for their parents to be contacted, the University could be held responsible if it does not contact the parents.
Or if a student is being dismissed from University and it is known they are suffering a mental health crisis the University should not continue to dismiss the student by email. If emails are automated, there should be processes in place that can override this.
These are real life situations families in this campaign have experienced.
