Picture a fly ash brick and hollow block plant on its B shift. The man in charge was, until last month, its sharpest hydraulic press operator. When the new press hand runs slow, he steps in and takes the levers himself. Output looks fine. Meanwhile two loaders stand idle because nobody told them which stack goes on the evening truck. The curing log for the day stays blank. A helper from the thekedar's crew is marked half-day without a word of explanation, and the argument reaches the owner's phone at ten at night.
None of this is laziness. He was promoted for his hands, and nobody showed him the new job. What follows is a way to build that new job on purpose. The promotion trap is one of five habits we see across kiln, mixer and yard plants, and the route below suits for block, paver, tile, precast, roofing and fittings units.
What changes on the first day in charge
The operator's day was one machine and one set of settings. The in-charge's day has a dozen moving parts. Write them down before you promote anyone, because the list is the syllabus.
- Taking muster at shift start and finding relievers for gaps before the pan mixer starts.
- Allocating hands across mixer, press or vibro table, pallet stacking, curing and loading.
- Receiving leave slips and knowing which ones he can grant and which go up.
- Talking to the thekedar or crew leader about absences, late arrivals and conduct.
- Walking the yard for dust masks, gloves, boots and blocked forklift lanes.
- Filling the shift report: output, breakage, rejects, downtime and curing batches.
- Handing over to the next shift with the open problems written, not just spoken.
Why skilled hands stall in the role
The machine is where he feels competent. Crew problems are messy, and nobody has told him how far his authority goes. So he drifts back to the press, the kiln burner panel or the batching console. Many new in-charges also supervise men they worked beside for years. Some are older than him. Some share his village. Correcting them feels like betrayal, so small lapses pass until one becomes a fight.
Owners add to the problem by bypassing him. If the plant head calls the loaders directly, the crew learns that the in-charge does not really decide. A development plan has to protect his authority as well as build his skill.
A twelve-week route for a new in-charge
- 1
Week 0: write the role on one page
List the decisions he owns, the ones he must refer and the people he answers to. Read it aloud to the crew and the thekedar on his first morning.
- 2
Weeks 1 and 2: shadow and then lead the muster
He watches the outgoing in-charge take muster and allocate the crew for three days. Then he leads while the old in-charge watches and stays silent.
- 3
Weeks 2 to 4: the five-minute start-of-shift talk
One safety point, the day's dispatch plan and any changed mould or press setting. Keep it standing, at the same spot, every shift.
- 4
Weeks 3 to 6: attendance and leave rules
Teach the plant's actual rules on late marks, half-days, swaps and leave. Hand him a printed note of the approvals that are his alone.
- 5
Weeks 5 to 8: settling a dispute at the shift
Practise with real recent cases: a docked half-day, a loader refusing a night truck, two crew leaders fighting over a forklift. He listens, checks the record and decides or refers.
- 6
Weeks 6 to 10: reading his own numbers
Each morning he reads yesterday's breakage, reject and curing figures and says one cause aloud. The plant head asks questions instead of giving answers.
- 7
Week 12: review with the plant head
Go through the shift cards, two handovers and any disputes. Agree what he now owns fully and what still needs support.
The shift card he carries
Date, shift and in-charge name.
Heads present against plan, relievers used and from where.
Crew allocation: mixer, press or kiln, stacking, curing, loading, yard.
Safety walk done at what time, and gaps found.
Output, breakage and rejects, with one likely cause.
Curing batches started and checked, with tank or chamber number.
Leave slips received, granted or referred.
Quarrels raised, and the outcome of each.
Open items for the next shift, written in full.The card is not paperwork for its own sake. It makes the job visible to him and to the plant head, and it turns a vague handover into a written one.
Each trade adds its own module. A tile line in-charge must read the roller kiln log, glaze weight checks and the sorting conveyor's grade split. A roofing line in-charge watches coil changes on the decoiler and scrap at each profile switch. In a chemicals unit, he signs the batch card for every ribbon blender load and checks drum seals before the forklift moves them. Fold these into weeks six to ten.
What the plant head must do differently
Coach once a week for thirty minutes, using the shift cards. Ask what he would do next time, rather than telling him. Route every crew complaint back through him, even when it would be quicker to fix it yourself. Stand behind his calls at muster; take up mistakes later in the cabin. Our manager development programme is built around this coaching rhythm rather than classroom sessions.
In precast yards the in-charge also directs crane signalling and rebar cage placement, so the route needs a safety module on lifting. The precast supervisor development page covers that variant. In block and paver plants the weak spot is usually crew output tracking, which links to performance management for block makers.
Signs the route is working
- Fewer night calls to the owner about crew quarrels.
- Curing logs filled on every shift, including the busy ones.
- Handover notes that the next in-charge can act on without a phone call.
- The in-charge on the yard floor, not standing at one machine for hours.
- Leave decisions he can explain by the written rule.
Your next thirty days
Pick one shift and one new or recent in-charge. Write his one-page role, print the shift card and book the weekly coaching slot.
