Backfill against growth hiring
| Backfill | Growth | |
|---|---|---|
| Trigger | A resignation, transfer or termination | A plan for additional capacity |
| Approval | Should already exist, since the cost is already in the budget | Requires a case and new budget |
| Warning | The notice period, typically one to three months | Whatever the planning cycle gives |
| Urgency | Work is already uncovered | The work does not yet exist |
| Risk | Rehiring into the same conditions that caused the exit | Hiring ahead of demand that does not arrive |
Organisations that treat every vacancy identically usually require a fresh approval for a backfill, which spends two weeks of the notice period on paperwork for a headcount that was never removed from the budget. Pre-approving backfill within an agreed headcount, with an exception process for anything else, converts that delay into search time.
Use the notice period
An Indian resignation typically comes with one to three months of notice, and longer at senior levels. That window is the whole advantage a backfill has over a growth hire, and it is routinely spent waiting.
- Open the role in the first week of the notice period, not after the exit interview.
- Have the leaver document the work while they are still doing it: recurring tasks with dates, access and system dependencies, in-flight items with their status, and the people outside the team who will need a new contact.
- Decide the coverage arrangement for the gap explicitly, and tell the people covering it when it ends. Temporary cover with no stated end becomes permanent by default.
- Ask the leaver what the role actually needs. A departing employee describes a job more accurately than the job description does, and has no reason left to protect it.
- Where the gap will exceed the search time, consider a fixed term or contract arrangement for the interim rather than distributing the work quietly across the team.
Decide what to backfill before reposting
A resignation is the only moment when a role can be changed without anyone losing anything, and reposting the same job description is the default that wastes it.
- Should the role exist as it was? Work accumulates around a person, and some of what they did belongs elsewhere or has stopped mattering.
- Should it be at the same level? A role filled by someone who grew into it may be posted at their exit level rather than the level it actually requires.
- Is this an internal opportunity? Backfilling from inside develops someone and creates a second, more junior backfill, which is usually a better problem.
- Did the reason for leaving belong to the role? Where the exit was driven by pay, workload, the manager or the absence of progression, hiring a replacement into unchanged conditions buys a repeat of the same exit within a year.
- Is the engagement type still right? A role that has become seasonal or project-based may be better as a fixed term engagement than a permanent one.
The exit interview is the usual instrument for the fourth question and the least reliable one, since departing employees soften their reasons. Patterns across several exits in the same team are more informative than any single conversation.
Planning the volume rather than reacting to it
- Forecast from attrition. A function of sixty with twenty per cent annual attrition needs twelve backfills a year before any growth, and that number belongs in the hiring plan.
- Track backfill separately from growth in reporting. Mixed together, a plan that looks delivered may be entirely backfill with no capacity added at all.
- Watch the chains. An internal move creates a vacancy behind it, and a three-step chain that is only approved one step at a time takes three times as long as it needs to.
- Time the concentration. Attrition clusters after appraisal and bonus payouts, so plan recruiter capacity for those months rather than distributing it evenly.
- Measure the gap, not just time to hire. Days the role was uncovered, including notice period and joining notice for the replacement, is what the team experienced.
- Keep the strong rejected candidates from the original search. The person who came second for this role six months ago is the obvious first call.
Frequently asked questions
What is a backfill?
A hire made to replace someone who has left or moved internally, as opposed to a growth hire that adds capacity. The cost is already in the budget, and the resignation gives a notice period of warning that a growth hire never provides.
When should we open a backfill role?
In the first week of the notice period. Waiting for the exit interview or the last working day spends the only planning advantage a backfill has, and the team then carries the gap for the whole of the replacement's own notice period as well.
Should we repost the same job description?
Only after checking. A resignation is the one moment a role can be changed without anyone losing anything, and work that accumulated around the previous person, the level, and the engagement type are all worth revisiting before reposting.
How do we forecast backfill volume?
From attrition by function. A team of sixty with twenty per cent annual attrition needs twelve backfills a year before any growth, and attrition clusters after appraisal and bonus payouts, so recruiter capacity should be planned for those months.
What if the person left because of the role itself?
Then hiring a replacement into unchanged conditions buys the same exit again within a year. Patterns across several exits in the same team are more reliable than a single exit interview, where departing employees usually soften their reasons.
How Engage plans backfill
Engage separates backfill from growth demand and opens the requisition against the resignation date rather than the last working day, so the notice period is search time instead of approval time. Attrition by function feeds the forecast backfill number directly, and the days a role stayed uncovered are reported alongside time to hire.
