Studies reveal that women in the US who work full time earn 79% of what their male counterparts earn. In April 2016, MTV created the 79% Work Clock to highlight this gender wage gap. An online tool lets users calculate when 79% of their working day is over. Users can then set their 79% Work Clock to sound an alarm at that time, reminding them that they are no longer being paid for their work. MTV gave away hundreds of clocks to workplaces across the country.
