Women responded to the call of need the country was displaying by stepping up to fill positions that were traditionally filled by men. They began to work heavy construction machinery, taking roles in lumber and steel mills as well as physical labor including unloading freight, building dirigibles (which are airships similar to air balloons), making munitions, and much more. Surprisingly, many women discovered they enjoyed the autonomy these jobs provided them with. It expanded their own expectations for womanly duty and capabilities. Unfortunately, this was reckoned as unnatural and as men began to return home from the war, the government instituted another propaganda campaign urging women to "return to normalcy".
