Why shoppers should support Tesco staff

Recently their union issued staff with rubber wrist bands stating “Tesco workers together”.
Staff have been informed by management that wearing these bands is construed as “bullying in the workplace”. Irish people should be aware of this attitude of management.
I urge shoppers to support Tesco staff. I have acquired a wrist band. I will wear it with pride any time I enter a Tesco store, as a sign of support for Tesco workers.
