Starting Monday Amazon workers can call a hotline to voice a complaint or concern about working conditions.
The Trade Union Unite says workers need a place to speak about the price they pay as a consequence of Amazon's drive for profit.
A union spokesperson says workers have already voiced concerns about timed toilet breaks unrealistic production targets and a high number of on-the-job injuries.
Amazon defended its business practices by saying the company offers excellent pay, excellent benefits, and opportunities for career growth.
