The retail and fast food workers union is calling for fast food giant Mcdonalds to overturn a new policy that would see employees unable to use the bathroom or take a drink outside of their allotted 10 minute break time.

A small group of protesters rallied around the Queen Street Mcdonalds on Friday to decry the proposal.

Shine Lawyers employment law expert Will Barsby says preventing water consumption poses a significant health and safety risk and exposes Mcdonalds to a higher percentage of injury claims.
