Workers’ right to access restroom

Currently, when an employment dispute arises regarding bathroom use where an employee has been prevented or punished in terms of employment, they are referred to OSHA who decides on each individual case. In addition, OSHA has ruled that where a worker has reasonably waited to visit a bathroom, or where an additional worker is not available, for replacement, in the worker's absence, then the worker is entitled to use the restroom or else the employer will be in breach of their fiduciary duties to the employee. Furthermore, employees must be paid for any break which equates to less than 20 minutes which includes bathroom use.
