Starting recap and vocabulary

A manufacturer can also be a landlord. A local strike can spread through workers linked by an industry. Different public institutions may respond differently to the same conflict.

Strike
A collective stoppage of work used to press demands.
Boycott
A coordinated refusal to buy, use or handle specified goods or services.
Arbitration
A process in which a third party considers a dispute and issues a decision under agreed or specified terms.
Injunction
A court order directing or prohibiting specified conduct; its scope must be read in the actual order.
Company town
A settlement in which a company owns or controls substantial housing or services as well as employment; arrangements vary.
01 · TRY

How did a dispute at one company become a conflict over a national rail network?

Build an actor-and-event map connecting company, households, union, city council and federal action. Calculate the fictional budget, then write a causal paragraph with one institutional mechanism, one competing explanation and two source IDs. Separate the June relief request from evidence of actual relief.

Calculate the budget and place four events in time. Write an evidence-based explanation separating company, union and public institutions.

Connect evidence and mechanism

Pullman in 1894: wages, housing and collective action

Begin with connected decisions

Suppose the institution paying your wages also collects your rent. Its accounting departments might treat those transactions separately; your household budget cannot. This is a useful starting mechanism, but it is not yet an explanation of a historical strike. We need dated evidence of decisions, organization, choices and institutional responses.

The source cards include excerpts and paraphrases from the 1894 United States Strike Commission report, an official transcription of a June 4 Chicago council resolution, two clearly labeled modern institutional accounts, and an invented budget. The two commission cards come from the same report. They are not independent witnesses, and the report’s description of company arguments is not a separately supplied company document.

Try: identify actors and connections

Draw a company box with two arrows: employer → pay and landlord → rent. Connect both to a household. Add workers and union connections, then the city council, courts and federal executive. Label each arrow as a documented action, a source’s interpretation or a mechanism you propose to investigate. Do not let an unlabeled arrow imply a measured causal effect.

The commission excerpt reports wage reductions alongside unchanged rent and contrasts the company’s public justification with the commission’s interpretation of business interests. The distinction matters: a report can contain evidence, attributed statements and evaluative conclusions. Neither official status nor confident wording makes every interpretation automatically established.

Ask whether an economic downturn fully explains a particular wage or housing decision. Conditions can constrain choices without making one response inevitable. To compare alternatives, we would need company accounts, contracts, household evidence and records of proposed settlements. Those full records are not supplied here. Do not invent a counterfactual settlement or assume all households had the same options.

Predict, calculate and interpret

Before looking below, calculate the fictional household’s pay, rent share and amount left after rent. All values refer to the same invented month-long interval. Other expenses are omitted only to isolate this mechanism.

ScenarioPayRentAmount after rentRent as share of pay
Before100208020%
After, rent unchanged75205526.67% approximately
Alternative, rent also reduced75156020%
Check the budget mechanism and its limits

Pay falls by 25/100 = 25%. With unchanged rent, the remainder falls by 25/80 = 31.25%. The denominator differs because the original remainder was eighty, not one hundred. Rent’s amount stays twenty while its share of pay rises to 20/75, about 26.67%. That is an increase of about 6.67 percentage points, not a nominal rent increase.

If rent falls to fifteen, the remainder is sixty, a 20/80 = 25% reduction. This alternative illustrates a different distribution of the adjustment; it does not show that the company actually adopted or could costlessly adopt it. We have not modeled property costs, other debts or the bargaining process.

These values are invented, not a transcription of a Pullman payroll. The report’s approximate average wage reduction does not imply that every worker had these hours, earnings or rent. “Amount after rent” is not income after every necessity and does not measure well-being, total annual loss or the probability of joining a strike.

Move from a household to a network

A work stoppage at the factory and refusal to handle its cars across railroads are different forms and scales of action. Use the union card to draw how connected occupations could transmit pressure beyond one workplace. Then add the membership boundary: the supplied National Park Service account identifies a union open across railroad occupations but restricted to white workers. Occupational breadth is not universal inclusion. The packet does not provide excluded workers’ own accounts.

Avoid a map with only “business” versus “labor.” A manufacturer, railroad managers, factory workers, other rail workers and households need not have identical interests within those broad categories. Nor should a local grievance committee be assumed to have ordered every later action. Mark the evidence for each connection and identify where additional organizational records would help.

Date public responses before comparing them

Date in 1894Supplied evidenceWhat the entry establishesWhat remains to investigate
May 11Modern archive explanationDate assigned to the factory strikeLocal decisions and participants’ accounts
June 4Council resolution transcriptionAn appeal for assistance and its stated rationaleDonations collected and relief delivered
July 2Modern archive explanationDate assigned to a federal injunctionThe order’s complete terms and application
July 3Modern archive explanationDate assigned to the troop orderOperational decisions and particular encounters

The council resolution portrays need and orderliness in a particular locality and earlier interval. Its twenty-thousand figure is a claim in an advocacy document, not a count independently verified by this lesson. The request that the mayor appeal for assistance is evidence of a proposed institutional response; it does not establish how much aid reached families.

A later account of conflict elsewhere during a larger dispute does not automatically refute that earlier local description. First align dates, places, actors and meanings of terms. This is a rule for testing apparent conflict, not a reason to accept either account without scrutiny. Look for independent incident records, correspondence and testimony when available.

The timeline also prevents “the government” from becoming a single undifferentiated actor. Local relief advocacy and federal judicial or executive action occupy different positions. The supplied summaries mention interstate commerce and mail delivery; they do not replace the actual court order or prove that every national strike was prohibited. This investigation concerns a historical conflict, not advice about current labor law.

Build a causal paragraph and challenge it

Write a paragraph with a mechanism, two source IDs and a competing explanation. For example, employer/landlord decisions can connect to household pressure, while the union network helps explain how a factory conflict could expand. The economic downturn supplies a broader condition, and institutional intervention changes the conflict’s constraints. Identify which part is reported and which is your inference.

Now test three tempting shortcuts:

  • A larger rent share does not prove a higher nominal rent.
  • A relief appeal does not prove relief delivery.
  • A report’s attributed company argument is not an independent company source.

Choose the additional record that would most change your account. A company letter could clarify management’s stated alternatives, worker testimony could illuminate experiences and choices, and an injunction could establish its specified terms. Each has a different role. A single new record still does not stand for everyone.

Transfer and continue

The separate transfer case asks about an earlier local description and a later wider event. Write the scope comparison before checking feedback. Do not answer by choosing whichever source aligns with your preferred side.

For the cumulative project, retain your first causal paragraph and revise one sentence after checking the budget or source chronology. Add a missing-evidence column to your actor map. A defensible historical argument can identify unequal power and meaningful worker agency while remaining precise about unobserved motives and outcomes.

High school: complete the budget, actor map and four-event timeline. Explain a claim you changed.

AP practice: connect industrial organization, labor strategy and government power using evidence and a counter-explanation. This bounded case is not the whole labor movement or a complete AP topic.

Introductory college: compare the complete commission report with company and worker records and the actual court order. Explain archival selection, source dependence and the limits of retrospective investigation. Do not present proposed research as already completed.

Worked example

In the invented budget, pay falls from 100 to 75, a 25% drop. The amount after rent falls from 80 to 55: 25/80 = 31.25%. Rent’s share rises from 20% to 20/75 ≈ 26.67%, despite its nominal amount remaining 20. If rent also fell to 15, the remainder would be 60, down 25% from 80. None of these invented values measures a historical household.
