Key Takeaways
- BLS reported 3.3 million quits and a 2.1% quits rate across U.S. nonfarm employment in July 2024.
- O*NET lists scheduling, travel, correspondence, reports, and office coordination among core executive administrative assistant tasks.
- There is no public national study that isolates virtual assistant support as the cause of lower administrative turnover.
- A credible retention test compares turnover, workload, quality, and manager load before and after a defined support change.
Administrative turnover is costly because it interrupts the work that keeps an organization moving: schedules, correspondence, records, meeting preparation, travel, reporting, and follow-through. But a useful retention analysis has to separate a plausible story from a proven result.
This page reviews the public evidence available for administrative work and explains how to test whether virtual assistant support improves retention. It does not claim that a virtual assistant automatically reduces turnover. Public national data does not establish that causal link.
The available turnover baseline
The U.S. Bureau of Labor Statistics reported 3.3 million quits across nonfarm employment in July 2024, a 2.1% quits rate. The series is useful for labor-market context because it measures voluntary separations, but it is not an administrative-assistant turnover rate. It should not be presented as one. BLS JOLTS, July 2024 also reports figures by industry rather than a specific executive-assistant occupation.
For the occupation itself, O*NET reports 502,800 executive secretaries and executive administrative assistants employed in 2024, projected employment decline of 1% or lower from 2024 to 2034, and 50,000 projected openings over that period. Openings represent a mix of replacement needs and growth. They are not a direct annual turnover measure.
| Public measure | What it can tell you | What it cannot tell you |
|---|---|---|
| JOLTS quits rate | National voluntary-separation conditions | Turnover for a particular admin team |
| Occupation employment and openings | Demand and replacement context for the occupation | Why a specific employee left |
| Internal HRIS records | Actual turnover and tenure in one organization | Whether a support change caused the difference without a comparison |
Why workload is a reasonable retention hypothesis
O*NET describes executive administrative work as high-level support that includes managing schedules, arranging travel, preparing reports, handling information requests, and coordinating office services. Its work-context data also shows daily email use for 97% of respondents, daily telephone conversations for 99%, and constant contact with others for 80%. See the O*NET occupation summary.
Those activities make workload a credible retention hypothesis. A role can become difficult to sustain when the same person owns urgent communication, complex calendar changes, routine follow-up, records, and exceptions at once. That does not mean every busy role leads to turnover, nor does it mean an external support model is suitable for every task. Confidential decisions, executive judgment, and relationship-sensitive work may need to remain with the in-house assistant.
What virtual assistant support can change
A virtual assistant can be useful when a team has clearly documented, digitally executable work that has stable quality standards. Common examples include calendar logistics, travel research, meeting materials, inbox sorting under defined rules, data cleanup, and routine follow-up.
The potential retention mechanism is indirect:
- Repetitive work moves to a documented support queue.
- The administrative employee has more time for judgment-heavy coordination and stakeholder work.
- Fewer urgent handoffs and missed follow-ups reduce avoidable friction.
- Retention may improve if workload and role quality improve together.
That sequence is a theory to test, not a benchmark. The evidence base does not support a universal percentage reduction in administrative turnover after hiring a virtual assistant.
A practical measurement design
Treat support as an operating change with a baseline rather than a one-time staffing decision. Capture at least 90 days before the change and 90 days after the team has stabilized.
| Metric | Calculation | Why it matters |
|---|---|---|
| Voluntary turnover | Voluntary exits divided by average headcount | Direct retention signal |
| Regrettable turnover | High-performing voluntary exits divided by average headcount | Separates priority losses from all exits |
| Workload mix | Hours in routine work divided by total tracked hours | Tests whether support is moving the intended work |
| Queue quality | On-time completion, rework, and escalation rate | Protects service quality while work is delegated |
| Pulse signal | Short, repeated workload and role-clarity questions | Detects strain before an exit occurs |
Use a comparison group where possible. For example, phase support into one administrative pod first while another similarly sized pod continues with its existing model. Keep role scope, manager, and seasonal workload visible in the analysis. A simple before-and-after comparison can confuse a market change, a manager change, or a hiring freeze with the effect of support.
Guardrails for an administrative support model
Support arrangements work best when the decision rights are explicit. Build a written task inventory that identifies what can be delegated, what requires review, what must stay internal, and the expected turnaround time. Add access controls, a named escalation owner, and a weekly review of rework or missed commitments.
For broader executive time context, the NBER review of CEO time-use research describes a multi-country study of 1,114 CEO diaries that found substantial variation in hours and time allocation. The study supports the idea that senior time is scarce. It does not measure virtual-assistant ROI or administrative turnover.
Caveats
- JOLTS is a national, industry-level labor-market series. It is not an administrative-assistant turnover series.
- O*NET task and work-context fields are occupational evidence, not evidence that a particular team has the same workload.
- No public national study identified for this review isolates virtual assistant support as the causal driver of lower administrative turnover.
- Retention should never be pursued by shifting an unmanageable workload to an external worker without capacity, quality, privacy, and fair-work checks.
