• Maintain visible field presence; verify workplace examinations, equipment inspections, and work conditions; monitor compliance with established requirements; and document coaching or corrective action as appropriate.
• Report incidents and near misses immediately; secure the area, notify required responders, preserve known facts and evidence, support investigations, and complete assigned corrective actions.
• When required, assume Incident Command within the assigned area by initiating emergency response, establishing scene control and accountability, coordinating communications and resources, and escalating in accordance with the Emergency Response Plan.
• Confirm employees are trained, qualified, and fit for assigned work; withhold assignments when requirements are not met and coordinate required training with the General Foreman, Safety, and Training.
• Translate the approved weekly plan into clear shift assignments, hazards, controls, sequence, resource requirements, and expected results; confirm employee understanding before work begins.
• Provide real-time coaching, recognition, and corrective feedback; document significant discussions and recommend appropriate hiring, development, performance, recognition, or succession actions.
• Apply attendance, conduct, performance, labor-relations, and Collective Bargaining Agreement requirements consistently, consulting the General Foreman and Human Resources as appropriate.
• Direct shift execution by comparing actual progress with the plan, inspecting active and completed work, correcting quality or productivity issues, and coordinating timely support.
• Identify constraints, changed conditions, missed or incomplete work, and cross-functional dependencies; resolve issues within delegated authority or promptly communicate impacts, options, resource needs, and recommended priorities to the appropriate General Foreman.
• Coordinate work with other Supervisors, Maintenance, Technical Services, and affected functions; verify commitments and take timely action to prevent unresolved dependencies from affecting safe and committed work.
• Control labor, overtime, equipment, materials, tools, and consumables against the approved plan; explain significant variances and recommend recovery actions.
• Complete accurate shift handoffs and maintain timely, audit-ready records covering safety, production, quality, workforce, equipment, cost, work orders, environmental requirements, and timekeeping; validate information before submission.
• Provide timely field feedback on plan assumptions, constraints, labor, equipment, work duration, quality, and resources used to improve future planning and execution.
• Perform other duties as assigned.
