The rate at which workers leave and must be replaced within a field crew or subcontractor roster. High churn drives up recruiting and onboarding costs, disrupts project continuity, and strains client relationships.
Churn
Related Terms
Rotational Worker
WorkforceA field worker employed on a fixed schedule of alternating work and rest periods, such as 14 days on and 14 days off. Subcontractors must account for rotation cycles when planning crew mobilisation and maintaining consistent headcount on site.
Field-to-Office Ratio
WorkforceThe number of field workers supported by each administrative/office employee. A ratio of 10:1 is common for paper-based operations; digitized operations often achieve 30:1 to 40:1.
Load Ramp
WorkforceA gradual increase in work volume or crew deployment at the start of a project or contract. Subcontractors use load ramps to scale up equipment, labour, and invoicing in a controlled sequence. Understanding the ramp schedule helps avoid resource gaps and cash-flow shortfalls early in mobilisation.
Independent Contractor
WorkforceA self-employed individual or company hired to complete specific work under contract, rather than as an employee. In field service, this covers most subcontractors supplying labour or specialised skills to operators and prime contractors. Independent contractors are responsible for their own taxes, insurance, and equipment.
Shoulder Season
WorkforceThe transitional period between peak and slow seasons when project volumes drop and scheduling becomes unpredictable. Subcontractors often face reduced call-outs, crew utilisation gaps, and tighter margins during these windows. Common in oilsands and construction work between summer and winter campaigns.
CLRC (Construction Labor Research Council)
WorkforceA U.S. research organisation that tracks and publishes construction labour wage rates and collective bargaining data. Subcontractors use CLRC reports to benchmark labour costs and support bid pricing on union projects.
