  • Get your OSHA 10-Hour card online — it's the universal first credential
  • Walk into 3 plumbing shops in your area (look up 'plumber' on Google Maps) and ask if they need a helper
  • Call UA Local 12 (Boston), Local 4 (Roslindale), or Local 138 (Worcester) about apprentice intake schedules
  • Buy a basic tool roll: tape measure, channel locks, pipe wrench, multi-bit screwdriver
