When men got sent to war , women had to take over their jobs . This included police officers , nurses/doctors , pilots, engineers and much more jobs . A significant job that may have proved women should have the equal vote was women who worked in munition factories . They were known as canaries (bright yellow birds) because of the chemicals around them , they were exposed and as a result it turned their skin, hair and nails bright yellow . This could lower life expectancy and prevent women from having children . This showed women were equal to men .
