The label uses the terms "coolie," "prison," and "filthy tenement-house workmanship."

Discuss why you think the union used these terms. Do we still have these biases today?

because they dont want people to not work enough and still get payed for their days work

The union used these terms to refer to people who do their jobs inappropriately but demand a fair wage, without deserving it.

Explanation:

Unions used such terms to show how labels referred to workers who did not work as they wanted, but demanded a fair and adequate wage. The use of perjorative words was intended to disgust those who were listening.

These terms are still used today, but more often, since labor laws are already well established, and unions are commonplace for any worker.
