No matter how difficult the going, a union must fight in every possible way to advance the principle of labor unity. Workers are indivisible. There can be no discrimination because of race, color, creed, national origin, religious or political belief. Any division among the workers can help no one but the employers. Discrimination of worker against worker is suicide.
Discrimination is a weapon of the boss.
Its entire history is proof that it has served no other purpose than to pit worker against worker to their own destruction. Labor solidarity means just that. Unions have to accept the fact that the solidarity of labor stands above all else, including even the so-called sanctity of the contract. We cannot adopt for ourselves the policies of union leaders who insist that because they have a contract, their members are compelled to perform work even behind a picket line. Every picket line must be respected as though it were our own.
