Colocation
Related Terms
Geofencing
WorkforceA virtual boundary set around a job site that triggers automatic alerts when workers or equipment enter or leave. Subcontractors use it to verify on-site attendance, automate timekeeping, and support accurate billing. It also helps clients confirm crew deployment without manual check-ins.
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.
Spare Capacity
WorkforceThe 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.
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.
Wage Theft
WorkforceWhen a client or prime contractor withholds earned pay from field workers or subcontractors through unpaid overtime, illegal deductions, or misclassified labour. It exposes subcontractors to legal liability if it occurs within their own crew management. Provincial labour standards apply regardless of contract wording.
CES (Current Employment Statistics)
WorkforceA monthly U.S. Bureau of Labour Statistics survey tracking employment, hours, and earnings across industries. Field service subcontractors use CES data to benchmark wage rates and spot labour market trends. It helps inform bid pricing and crew cost projections in competitive markets.
