Staffing a three-month peak: hire, borrow, agency or subcontract, and when to start
The greenhouse glazing plan shows an eighteen-person gap for three months. An agency offers a quick start, another project may release installers and management proposes permanent recruits. None of the proposals yet explains orientation, supervision or what happens after the peak.

Make the choice from the required skills and work packages, rather than from one headcount shortfall. Hiring, transferring employees, agency support and subcontracting place different responsibilities and commitments on the project. Compare actual offers, availability, supervision and exit conditions. Derive the start date from those confirmed lead times; six weeks might suit one plan and fail another. The useful deliverable is a staged staffing decision with a fallback and an end plan.
Compare routes before committing arrivals
- Locate the demand. Break the peak into weeks, skills and available workfaces. Check the workload against the labour plan and confirmed existing capacity. Separate a continuing skills shortage from a brief volume increase; they may call for different decisions.
- Obtain comparable proposals. For each route, record what is supplied, when it is genuinely available and who controls or delivers the work. A subcontracted package includes a scope and interface arrangement; it is not simply another way to purchase indistinguishable hours.
- Compare the complete cost and risk. Include recruitment or fees, travel, orientation, supervision, equipment, learning time and agreed commercial conditions. Ask the appropriate payroll, labour or contract adviser to confirm applicable terms. Keep uncertain figures identified instead of presenting the cheapest hourly quote as the cheapest finished work.
- Check the receiving capacity. Name supervisors and competent instructors, verify role requirements and confirm access, tools and facilities. Stage arrivals where necessary. Twenty people arriving Monday do not create twenty immediately productive people if the site cannot receive them properly.
- Work back from ready work. Use confirmed recruiting, release, mobilization and orientation periods to set decisions and arrival dates. Record their owners and a reasonable project contingency. Identify what happens if a transfer or supplier commitment fails before the peak starts.
- Plan the reduction now. Assign return dates for borrowed employees, agreed package completion and the appropriate employment or agency decisions. Have authorized people confirm the relevant obligations. Review the forecast as the peak develops so an unneeded crew is not retained merely because no end decision was prepared.
Common mistakes
- Comparing only quoted hourly prices.
- Counting an unconfirmed transfer as available capacity.
- Bringing everyone at once without receiving resources.
- Leaving the peak's end to an informal future conversation.
Checklist

- Comparable confirmed staffing proposals.
- Complete cost, supervision and conditions.
- Staged arrivals and orientation capacity.
- Owned lead times and fallback.
- Agreed reduction and completion decisions.
Check your understanding
A supplier can provide the full headcount next week, but the receiving supervisors are unavailable. Is the peak covered?
