Rabbi Zalman Kastel is the national director of Together for Humanity, an organisation that seeks to foster intercultural understanding among school students.

He's seen first-hand how 'burdened' some students and teachers feel as they try to keep up with their work, and the impact of their never-ending to-do list.

He reflects on the purpose of work, the importance of the Sabbath, and ways to respond to burnout from the Jewish perspective.
