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.
Journeyman
WorkforceA tradesperson who has completed an apprenticeship and holds a recognised certification in their trade. Subcontractors often bill journeymen at a higher labour rate than apprentices. Many project specs or collective agreements require a minimum ratio of journeymen on site.
Slip Fill
WorkforceA temporary worker brought in to cover a single shift vacancy without joining the regular crew rotation. Common in oil sands and remote site operations when a crewmember is absent unexpectedly. Subcontractors often use slip fills to maintain headcount without committing to long-term hires.
Retention Bonus
WorkforceA 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.
Energy Wheel
WorkforceA visual planning tool showing seasonal cycles of activity across oil & gas and construction sectors. Subcontractors use it to anticipate busy periods, align crew availability, and time equipment investments. It helps field service companies reduce downtime between contracts.
Skilled Trades Pipeline
WorkforceA roster of pre-vetted tradespeople a subcontractor can mobilise quickly for upcoming projects. It includes workers at various certification levels, from apprentices to journeypersons. Maintaining a strong pipeline reduces downtime between contracts and supports rapid crew scaling.
