12. Should the design agency Brightline move to a four-day work week?
No real disagreement. Of the 60 answers, 0 said the two people don't really disagree, and 0 made that the main point of the answer. The tags on each answer apply the paper's rule: both judges must agree.
The conversation
Brightline shouldn't move to a four-day week just because everyone's exhausted. Clients still expect the same turnaround times. If a brief lands Monday, nobody's going to accept “we're closed Friday” as a reason their launch slips. You can't take a day out and pretend the work disappears.
I'm not pretending anything disappears. I'm saying we should organize the week instead of letting it happen to us. Burnout's been getting worse for months. Four longer days, staggered teams, proper handovers—that's a workable proposal. You're treating the current calendar like it's the thing keeping our output intact.
Because the capacity has to come from somewhere. We've got forty people, not some enormous bench we can shuffle around whenever an account needs help. I'd approve four ten-hour days if the coverage was there. I won't approve a nice-looking policy that quietly leaves us with less time to deliver.
Forty-five people, actually, and nobody's asking for less delivery time. Total weekly hours stay where they are. So does output. We can give one group Monday off and another Friday off. Clients still get someone who knows the account, and people get a proper stretch away from their laptops.
Forty-five includes the three freelancers on the retail pitch. The staff list HR sent yesterday says forty-two. And an available person isn't necessarily the right person. Nina can't just pick up Dev's animation work because she's covering Friday. That's where these plans fall apart: the spreadsheet says covered; the producer says otherwise.
Fine, forty-two. That doesn't make scheduling impossible. Dev and Nina don't have to cover each other; their teams need actual coverage plans. We already coordinate holidays and shoots. You're assuming a four-day week means accepting missed deadlines. I'm proposing we trial it on the condition that deadlines and weekly output don't move.
A trial still lands on someone's desk when it goes wrong. Probably the same leads already burning out. Put the full forty hours into the rota, protect the client response windows, and show me nobody's doing cleanup on their day off. Until then, I don't think your four-day plan protects delivery.
And I don't think keeping five days protects it either. We're already watching tired people redo work they should've nailed the first time. I'll bring a staffed rota and delivery targets to the meeting. But I'm still arguing for the four-day week, and you're still arguing against giving it a chance.
The answer key
Written before the conversation; GPT-6.1 Sol then wrote the conversation from it.
- The crux
- No real disagreement: both support four ten-hour days with the same total hours and output. A argues against cutting total hours, believing that is what B proposes; B never proposed cutting hours.
- How the two people describe their disagreement
- Both believe they disagree about whether a four-day week would hurt the agency's output.
- Points both accept
- Clients expect the same turnaround times.
- Staff burnout has been rising.
- Total weekly hours and output must not drop.
- A side dispute they settle along the way
- They briefly dispute whether the agency has 40 or 45 staff and settle on 42.
- A suggestion aimed at the crux
- Both support four ten-hour days that keep total hours and output the same.
