The modal worker is a tender on an increasingly instrumented line, so the trend is fewer operators covering more furnaces rather than none.", "outlook": "Expect continued slow headcount decline as instrumentation consolidates multiple furnaces under one operator; the survivors are the ones who also maintain and troubleshoot the equipment.", "what_would_raise_it": { "levers": [ { "dimension": "embodiment", "change": "If OSHA's long-pending Heat Injury and Illness Prevention standard (rulemaking opened 2024) plus confined-space/hot-work permit enforcement makes remote-only or robotic intervention non-compliant without an attendant physically present, the on-floor charging/drawing/thermocouple-swap tier stays human and gains a required standby role per furnace bank", "plausibility": "plausible", "would_add": 3 }, { "dimension": "task_resistance", "change": "Genuine two-tier structure: once PLC/closed-loop control absorbs all gauge-watching and curve-holding, the residual job is abnormal-condition response — refractory spall, clinker jam, burner flameout relight, thermocouple drift diagnosis.
