Spare Capacity

The percentage of a technician's shift spent on hands-on productive work versus travel, waiting, or admin tasks. For subcontractors, low wrench time means billing inefficiencies and reduced daily output. Clients often track it to evaluate crew productivity on site.

Organised work stoppages or slowdowns by unionised labour, such as strikes or lockouts, that can halt site operations. Subcontractors may face project delays, contract disputes, or force majeure claims as a result. Review your MSA carefully for provisions covering liability during third-party industrial action.

Retaining trained field crews on payroll during slow periods to avoid rehiring and recertifying workers when activity resumes. Common in boom-bust cycles, it protects workforce continuity but strains cash flow. Subcontractors must weigh bench costs against the risk of losing certified tradespeople to competitors.

The percentage of available crew hours that are billable or actively deployed on a job. Low utilisation means workers are on standby or idle, cutting into margins. Subcontractors track this metric to assess workforce efficiency and bid future projects accurately.

The process of assigning and deploying field crews or equipment to a job site. For subcontractors, dispatch timing affects mobilisation costs, crew scheduling, and billable hours. Clear dispatch records also support accurate invoicing and dispute resolution.

Occurs when two unrelated companies — such as a labour agency and a subcontractor — are considered co-employers of the same worker. Both parties may share legal responsibility for wages, overtime, and labour standards compliance. Field service firms must understand this to avoid unexpected liability for workers hired through third-party staffing arrangements.
