Lesson 1 of 6Step 1 of 5

Choose support that does the work you need

Affirmative · Constructive speech
Read the fictional case: The four-day workweek
Affirmative · Constructive speech

Resolution A four-day, 32-hour standard work week should replace the current five-day, 40-hour model

Fictional round packet: 24 volunteer workplaces, covering offices, retail and distribution, joined a six-month comparison. Half were assigned by lottery to 32 hours at unchanged weekly pay; half kept 40 hours. Both groups maintained an output index of 100. Absence averaged three days per worker in the shorter-week group and five in the comparison group; these counts were not adjusted for scheduled days. Customer coverage was maintained, but payroll in the shorter-week retail and distribution sites was 8% higher; office payroll was unchanged. Healthcare and other continuous-service industries were not included. For this practice round, the affirmative defends replacing the normal 40-hour model with a 32-hour standard at unchanged weekly pay; it does not claim every shift must be identical. The negative challenges whether the benefits justify the costs of that replacement.

Start with the claim you want to establish, then choose evidence that addresses it. Pay, time, output, absence and coverage measure different consequences. Their relevance depends on the argument.

Evidence can support one part of a case without proving the whole resolution. Explain the connection and choose what additional reasoning or comparison the audience needs.

Inspect the fictional source

Fictional source extract, Comparison B: 24 volunteer workplaces, six months, allocation by lottery. Weekly pay unchanged. Output index: 100 in each group. Absence: 3 days per worker at 32 hours, 5 at 40 hours; not adjusted for scheduled days. Coverage maintained. Retail/distribution payroll: 8% higher in the shorter-week group. Offices: no payroll increase. No healthcare sites.
Workers gained time without losing weekly pay.

Together with the change from 40 to 32 hours, this supports a time benefit at the same weekly pay.

Output was maintained in the comparison.

This supports the output claim in the studied settings. It is not a measure of payroll cost.

The change was costless in every workplace.

This part of the record contradicts a costless-change claim. Use the benefit without pretending it removes the cost.

Choose a claim. The highlight shows the part of the record to inspect.

  1. Name the claim

    Identify the outcome or connection you need to support.

  2. Choose the measure

    Use the source detail that addresses that claim.

  3. Explain the significance

    Show why that result gives your side a reason in this round.

The negative challenges whether the benefits justify the costs of that replacement.

  1. Affirmative · Claim
    The shorter standard can give workers usable time at unchanged weekly pay.

    This is a worker-outcome claim.

  2. Affirmative · Support
    The treatment moved from 40 to 32 hours while weekly pay remained unchanged.

    This directly supports the time-and-pay part of the claim.

  3. Different measure
    The output index stayed at 100.

    This helps with a feasibility argument. It does not by itself show the payroll cost vanished.

  4. Affirmative · Case use
    Use the time benefit and output support together, then compare them with the recorded cost.

    The evidence now serves a developed affirmative reason.

Choose the evidence for the claim, then explain how it helps the case.

Your turn

Affirmative · Constructive speech

Choose two findings that support a worker-benefit argument. Explain their role and one important limit.

Read the fictional case: AI and the future of work
Affirmative · Constructive speech

Resolution Advanced AI will on net improve outcomes for workers

Fictional round packet: a two-year review of 30 employers records 300 retained workers receiving 4% higher inflation-adjusted pay and working 37 rather than 40 hours per week after AI adoption. Sixty entry-level roles were removed and 40 technical roles added. Of the 60 displaced workers, 18 entered the new roles, 24 found work elsewhere at 8% lower pay, and 18 were still unemployed six months later. The other 22 new roles went to different applicants. The review does not isolate AI from every other change or forecast the whole economy. The affirmative argues that productive tools can improve pay and time for many workers. The negative argues that concentrated losses and barriers to new work can outweigh those gains.

Resolution Advanced AI will on net improve outcomes for workers

Read the practice task and fictional case

Choose two findings that support a worker-benefit argument. Explain their role and one important limit.

Fictional round packet: a two-year review of 30 employers records 300 retained workers receiving 4% higher inflation-adjusted pay and working 37 rather than 40 hours per week after AI adoption. Sixty entry-level roles were removed and 40 technical roles added. Of the 60 displaced workers, 18 entered the new roles, 24 found work elsewhere at 8% lower pay, and 18 were still unemployed six months later. The other 22 new roles went to different applicants. The review does not isolate AI from every other change or forecast the whole economy. The affirmative argues that productive tools can improve pay and time for many workers. The negative argues that concentrated losses and barriers to new work can outweigh those gains.

Your response

You can return to the practice whenever you want.

One model response

I use the 4% real-pay gain and the move from 40 to 37 weekly hours for 300 retained workers. Together they support benefits reaching workers as income and usable time, rather than only company output. They do not establish the outcomes for displaced workers or isolate AI from every other change, so the wider affirmative case needs a transition comparison and an argument about the forecast.

This is an income outcome relevant to worker welfare.

The response selects relevant worker outcomes and gives them a positive role. It keeps the measured group separate from the overall resolution without abandoning the supported reason.

Common mistakes to avoid
  • Choosing an impressive number that measures a different claim.
  • Expecting one source detail to prove the entire resolution.
