The press operator at a block yard has run the egg-laying machine for nine years. He sets mould height by eye and hears when the mix is too dry. When the old supervisor leaves, the owner hands him the crew. Within a month he bellows at the dawn muster. His fellow villagers get the easy sprinkling work in the curing yard. Attendance lives in a pocket diary. Two good off-bearers quit. Nobody ever taught him the job he now holds.
Our sector page for kiln, press and mixer plants records it as a named pattern. Yard supervisors tend to be the finest operators, yet few were ever taught crew handling, attendance or dispute work. Here we trace the signs, tally the bill, explain the repetition and offer a remedy that keeps supervisors on the yard nearly throughout.
Symptoms at muster and on the press
- A noisy, slow muster. Posts are filled by shouting, so the press, pan mixer and curing yard begin late and short-handed.
- Lopsided posting. Sprinkling, tractor driving and overtime go to the supervisor's circle; off-bearing and bag charging go to everyone else.
- A pocket-diary muster roll. Half days, late arrivals and cash advances are jotted informally, then fought over when the envelopes are handed out.
- Quarrels decided by volume. A row between crews who speak different languages, or over the count of blocks per thousand, ends with the loudest man winning.
- Safety by old habit. He checks what he checked as an operator, which may not include mixer gloves, press guards or the height of cured stacks.
- Silent departures. Workers vanish, and the only explanation offered is that they 'went to the village'.
The bill the yard pays
Output slips when the press waits for its crew or the wrong hand ends up at the mould. Wage quarrels eat the owner's evenings each month. Skilled off-bearers and mixer men leave, so every season starts with teaching. The supervisor often wears out too, squeezed between an owner chasing pallets and a crew that has stopped trusting him. Some plead to be sent back to the press. Others move to a yard that pays operators better.
Why promotion keeps replacing preparation
In a small yard, the supervisor's chair is the only prize an owner can hand a strong operator. No senior operator grade exists, so climbing means leaving the press. The newcomer is expected to pick up crew handling the way he picked up mould setting, by doing it. Nobody shows him a fair posting, a clean muster roll or a correction that leaves a man's dignity intact. Meanwhile the works manager, chasing dispatch, hears about him only when a crew walks off.
Five observations before any training
- Attend three dawn musters and time how long every post takes to fill.
- Set the diary or register beside the wage sheet for a recent month and mark mismatches.
- Ask a few crew members, privately, how posts and overtime get shared.
- Read last season's leavers and note whose crew each one belonged to.
- Ask each supervisor which part of the role troubles him most. Answers tend to be candid.
Six coaching blocks that change the yard
- 1
A muster board, not a muster shout
Every post on the yard listed on a board and filled in before the first worker reaches the gate. Heavy and light posts rotate by a written rule anyone can read.
- 2
Attendance off the diary
A register or the thumb machine at the gate, with half days, late arrivals and advances entered on the day and shown to the worker. Envelope-day rows shrink fast.
- 3
The private correction
Role-play correcting a late man or a skipped glove: away from the crew, calm, the fact stated, the expectation repeated. A written warning follows only on repeat.
- 4
A first step for quarrels
Separate the parties, hear each, write a line, decide, or hand it up to the works manager by the closing siren. The same route for every crew and every language.
- 5
A three-point safety walk
Mixer gloves, press guards and stack height checked and initialled each shift. The works manager glances at the sheet every Saturday.
- 6
A standing slot with the works manager
A short sit-down each week on absences, quarrels, leavers and one difficulty the supervisor raises himself. Most coaching happens here.
Deliver these blocks on the yard itself, in short weekly sessions spread over two or three months, never as a classroom course. Our programme for first-line managers can take this shape. For yards where cranes, riggers and fixing crews add layers, see the precast supervisor coaching plan.
Picking the next supervisor
Watch for the operator whom others already approach for help. He explains rather than shouts and keeps his word on small things. Mould skill matters, but temperament matters as much. Add a senior operator grade, better paid, for men happier at the mould, so supervision becomes a choice. Grades and crew attendance on block lines are covered on the hollow and solid block yards page. Preparing a man before he takes the chair is the theme of our guide to first-time yard supervisors.
Begin at the dawn muster
This week, attend one muster on each crew. Hang a muster board on the slowest. Book a short weekly sit-down with each supervisor. Those three moves begin the change before any formal session. For help shaping the coaching and the operator grades, describe your crews and supervisors to us.
