O, Labor Day, O, First of May,
Welcomed and honored on land and on sea.
Winter so drear must disappear,
Fair days are coming for you and for me.
We, of the old world, building the New,
Ours is the will and the power to do;
Then let us sing, hail to the Spring–
Hail to the Day we can strike to be free!

Banner so red, high overhead,
Hated and feared by the powers that be!
In every land firmly we stand;
Men of all nations who labor are we.
Under one banner, standing as one,
Claiming the earth and our place in the sun.
Then let us sing, hail to the Spring–
Hail to the Day we can strike to be free!

O, Labor Day, O, First of May,
Warm with the gleam of the bright days to be!
Join in the throng, fearless and strong–
One mighty Union of world industry.
Shoulder to shoulder, each in his place,
Ours is the hope of the whole human race.
Then let us sing, hail to the Spring–
Hail to the Day we can strike to be free!
