Role design and job descriptions for Plumbers: where a helper ends and a fitter begins
On a plumbing site everyone does a bit of everything, until a job goes wrong and nobody knows who was responsible. Written roles settle that and give helpers a path.

In a plumbing gang the fitter cuts and joins, the helper digs and carries, and on a busy day the helper holds the torch while the fitter fetches pipes. This flexibility is useful. The cost comes when a joint leaks a week later and nobody can say who made it, or when a helper asks for a raise and the owner cannot say what the next step is.
Roles do not have to be rigid. A one-page description for each of helper, fitter, senior fitter and gang leader, with tasks, tools and who they report to, is enough. It tells a newcomer what to expect, tells the owner what to check, and lets a helper see what to show in order to move up.
How to set it up
1. List what actually happens on sites
Spend two days on different sites and note the tasks each person does. Use plain words such as measure, cut, thread, join, test for leaks and clear the site.
2. Group tasks into four roles
Helper, fitter, senior fitter and gang leader. Put tasks that need judgment, such as pressure testing and reading a drawing, with the higher grades.
3. Write one page per role
Purpose, main tasks, tools used, who supervises and what the person may decide alone. Keep the language simple enough to explain in Hindi or Kannada or whatever the crew speaks.
4. Add the step up
For each role, write three or four things a person must show to move up, such as a leak-free test on a real bathroom. Pay follows the role, not the age of service.
5. Share and adjust with the gang
Read the pages aloud with a gang, listen to what is missing and correct. A role page that the team does not recognise will not be used.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Ask a helper and a fitter separately what the helper is expected to do and compare answers.
- Count the last promotions and write down what each person was asked to show.
- Look for tasks that nobody owns, such as site clearing or fittings return.
- Check whether a joint failure last month could be traced to a person.

Questions owners ask
Not if they describe the usual work and name who decides in a pinch. A helper can still hold a torch, but the record shows who made the joint, which is what you need.
One page, in the language of the crew. If it needs two pages or technical terms nobody uses, it will not be read. Detail belongs in training sheets for specific tasks.
Promotion by showing real tasks on a live job is fairer than a formal test. Let the senior watch, write the date and sign, so the decision can be explained to everyone.
