Experimental Design
The vignette experiment
All respondents are read one hypothetical workplace scenario. The scenario describes a 26-year-old worker who has been employed for two years at a shop of the respondent’s own type — clothing retail, restaurant, or spa, pre-filled from the main survey — and currently earns Rs. 18,500 (approximately $200) per month. The worker speaks privately to the employer and makes one workplace request. Employees answer the follow-up questions from the perspective of the worker; employers answer from the perspective of the employer.
The vignette randomizes three features:
• Request type. Respondents are assigned with equal probability to one of three request categories: a 20 percent salary increase, a non-wage workplace amenity, or a promotion to a supervisory role. Within the amenity category, respondents are further assigned with equal probability to one of three specific amenities that they make a request for: a harassment-reporting mechanism, two fixed 15-minute breaks during the workday, or permission to sit during quiet periods when there are no customers.
• Framing. The request is framed either in rights/fairness-based terms or in practical/instrumental terms.
• Protagonist gender. The worker is described either as Priya, a female worker, or Rahul, a male worker.
The exact wording for each vignette cell is reported in the Appendix, including the Hindi translations. Randomization is at the individual respondent level. Each respondent is independently assigned the protagonist gender, request type, framing, and, when applicable, amenity sub-type. Employees and employers from the same shop are therefore not necessarily assigned to the same vignette. In the main analysis, request type will be coded at the three-category level: salary increase, amenity, and supervisory role. Analyses that separate the three amenity sub-types are treated as exploratory, given the smaller cell sizes.
Link to the intervention. The vignette experiment motivates the content of the negotiation support intervention in Part 2. In particular, it allows us to compare employer stated receptiveness (employer Q5) with employee expectations (employee Q5) by request type. If workers underestimate employer receptiveness to some requests, especially non-wage amenities, this creates scope for light-touch support that helps workers identify feasible requests and prepare how to make them. The belief-correction component of the intervention draws directly on these employer-side responses by informing workers about employers’ reported receptiveness to amenity requests relative to salary requests.
Part 2: Negotiation support intervention
Treatment assignment
Among eligible workers, assignment is a 2×2 randomized design at the individual employee level. Eligible workers are employees who report interest in receiving negotiation support in the survey module (employee Q11) and share a WhatsApp number through which they can receive the support.
Workers are randomized into different treatment arms, with treatment stratified by worker gender × treatment status in the parent project, producing four strata. Within each stratum, eligible workers are assigned with equal probability to:
• Treatment arm vs control arm: full negotiation support (`T_wins`) or control (`C_wins`).
• Belief correction on vs off: Receive belief correction message or not. Workers assigned to receive a belief correction message see a paragraph reporting employers’ stated receptiveness to amenity requests relative to pay raises. This assignment is conducted independently within each treatment arm.
Randomization is conducted in weekly cohorts by the research team on a computer and not on the platform used to deliver the WhatsApp chat support. Each Friday, newly eligible workers surveyed since the previous Friday are randomized into one of the four experimental groups.
Treatment content
Within a few days of randomization, workers assigned to `T_wins` receive a structured WhatsApp flow called “Apni Baat” — translated as “Your Own Say”. The flow first asks workers to choose a request topic from a short menu. Workers assigned to “belief correction on” then receive a one-paragraph message reporting employers’ stated receptiveness to amenity requests relative to pay raises.
The flow then delivers ten short lessons on simple negotiation principles: giving a reason, linking the request to a benefit for the shop, being specific and polite, choosing a calm and private moment, offering a trial, and treating an initial “no” as “not now.” It also presents the employer’s likely perspective, provides an editable example script matched to the worker’s shop type, and offers a line the worker can use if the employer initially says no. The flow is rule-based, uses numbered menus, and relies on fixed, pre-translated English and Hindi content.
Control content
Workers assigned to `C_wins` receive an introductory message identical to that of the treatment group and are asked to choose a request topic from the same menu. They then receive no communication for approximately three weeks. At the end of this period, they are asked the primary outcomes administered to all participants, after which they also receive the full negotiation support flow. The treatment-control comparison therefore compares treated and control participants in the three-week window before the control group receives the support content.
