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.
Wrench Time
Related Terms
Vertical Joint Employment
WorkforceA legal finding where both a subcontractor and a client company are considered employers of the same field workers. This exposes subcontractors to shared liability for wages, overtime, and labour standards violations. Regulators in oil and gas and construction actively scrutinise these arrangements.
BLS (Bureau of Labor Statistics)
WorkforceA U.S. federal agency that tracks wage rates, employment trends, and labour costs by trade and region. Subcontractors use BLS data to benchmark crew rates and support bid pricing. It also publishes injury and fatality statistics relevant to oil and gas and construction fields.
Shift Rotation
WorkforceA scheduled cycle that determines when field crews work and rest, commonly structured as 14 days on and 14 days off in remote oil and gas sites. Subcontractors must account for rotation schedules when planning crew mobilisation and labour costs. Misaligned rotations between a subcontractor and prime contractor can cause costly coverage gaps.
Spot Capacity
WorkforceAvailable labour, equipment, or service bandwidth that a subcontractor can deploy immediately without prior commitment. Primes often source spot capacity to fill urgent gaps during peak demand or project overruns. Rates for spot capacity are typically higher than contracted rates.
Job Openings Rate
WorkforceThe percentage of unfilled positions relative to total jobs in a sector at a given time. For subcontractors, a high rate signals strong demand for field crews and leverage in rate negotiations. It helps forecast labour shortages before mobilising for large campaigns.
JOLTS (Job Openings and Labour Turnover Survey)
WorkforceA monthly U.S. Bureau of Labor Statistics report tracking job openings, hires, and separations across industries. Field service contractors use it to benchmark labour demand and anticipate competition for skilled tradespeople. Rising JOLTS numbers often signal tighter crew availability and upward pressure on wage rates.
