Workforce Glossary Term

Retention Bonus

A lump-sum payment offered to keep skilled field workers or subcontractors committed through a project's duration. It is typically paid at a set milestone or project completion. Primes use it to reduce crew turnover during long campaigns or tight labour markets.

Related Terms

Spare Capacity

Workforce

The portion of a subcontractor's available workforce, equipment, or service hours that is not currently committed to active contracts, representing untapped revenue potential that can be offered to clients on short notice or used to absorb surge demand without turning down work.

Fly-In/fly-Out (fifo)

Workforce

A rotation model where workers are flown to remote job sites for a set number of days, then returned home. Subcontractors must account for mobilisation costs and crew availability when bidding FIFO contracts. Rotation schedules vary widely, such as 14 days on and 14 days off.

Field-to-Office Ratio

Workforce

The 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.

Churn

Workforce

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.

Horizontal Joint Employment

Workforce

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.

Circadian Science

Workforce

The study of how the body's internal clock affects alertness, performance, and safety during shift work. Subcontractors use it to design smarter rotation schedules that reduce fatigue-related incidents. Regulators increasingly reference circadian principles in hours-of-service and fatigue management requirements.
