From Monday (2 November) teachers, teaching assistants, catering staff, dinner ladies, caretakers, cleaners and school office staff will be able to claim the discount on groceries at stores across the UK.
All they'll have to do is present their school photo ID card at the till at any of Mozzas' 498 stores, with the discount lasting 'until after Christmas'.
David Potts, Morrisons Chief Executive, said: "Teachers and school staff are facing many challenges and the education of our children has never been more important.
"This discount is our way of saying thank you as they continue to care for and educate our kids."
What's that I hear you say? 'That's all well and good, but what about our NHS heroes?' Fear not - they've enjoyed the discount since April.
NHS workers are also granted a dedicated shopping hour from 6am-7am (Mon-Sat) before stores open to other customers, and school workers will now be able to use this exclusive shopping window too.
In March, the supermarket donated £10 million worth of groceries to food banks to help them meet high demand.
Staff on its bakery, as well as its fruit and veg teams, put in extra hours to make sure the deliveries were ready on time.
Extra tinned goods and pastas were also sent out to shops before being taken to local food banks.
Speaking on BBC Breakfast about the initiative, Potts said it was the company's duty to help those in need.
He said: "As a food maker and shopkeeper we are uniquely placed to help.
"We know food banks are finding life very difficult and running our manufacturing sites for an extra hour each day to help restock them is the right decision at this time.
"Our staff - along with ourselves - follow the Public Health England advice. We listen quite carefully to the authorities and we provide the opportunity to be protected at the tills.
"We've closed down many counters, we've become much more of a self service business; (we are) washing hands and taking all of the social distancing measures."
