Who does the dispatch:
- Construction site supervisors and "mistris" (master craftsmen) coordinate 20–100 workers per site across 3–10 sites
- Factory labor contractors maintain rosters of 50–500 workers and fill shift vacancies on demand
- Security guard agency supervisors match guards to posts, covering last-minute sick calls and absent workers
- Event and exhibition labor coordinators hire daily-wage workers for shows in Bangalore, Mumbai, NCR exhibition halls
- Primary tool: personal mobile phone. The contractor scrolls through WhatsApp chats or saved contacts, calls each worker, waits for a missed-call confirmation, then calls the next
- WhatsApp groups: one-way broadcast channels where the contractor types "need 5 helpers tumkur site tomorrow 6am" and waits for replies — most workers reply with a voice note or missed call
- Excel or paper register: the coordinator maintains a hand-written or Google Sheet roster with worker names, skills, and phone numbers. Updated manually after every shift
- "Jobwork contractor" (registered under the Contract Labour Act): a formal intermediary who maintains the worker relationship. Gets a 5–10% margin on the daily wage bill
- A contractor filling a 10-person shift manually makes 15–25 phone calls. Average call duration: 90 seconds. On a bad day (workers don't answer, numbers are wrong, workers cancel last-minute), this takes 2–3 hours
- Workers miss calls. The contractor must try a second and third worker, creating a cascade of follow-up calls
- No-show tracking happens after the fact: the supervisor realizes at 7am that 2 workers didn't show. The site has already been understaffed for 2 hours
- In tier-2 cities (Tumkur, Dharwad, Raipur), contractor uses personal phone with a single SIM. Outgoing call cost: approximately 60 paise per minute on a standard prepaid plan. A busy day of dispatch calls runs ₹20–50 in airtime
- The contractor's own time is the biggest leak: if his hourly cost is ₹100–200, 2.5 hours of daily dispatch calling costs ₹250–500 per day in opportunity cost
