5.5 Alternative Staffing Practices: RPO, Temporary Agencies, Job Sharing & Remote Workers
Key Takeaways
Recruitment process outsourcing (RPO) transfers all or part of the recruiting process to an external provider that acts as an extension of the employer's talent acquisition team.
Temporary agency workers are placed and usually paid by an agency while the client directs daily work; ILO Convention No. 181 says private employment agencies should not charge fees to workers, subject to limited exceptions.
Job sharing splits one full-time position between two people who divide the hours, duties, and pay, which retains skilled staff who want reduced hours.
Cross-border remote work can create tax, social-security, employment-law, and immigration obligations in the country where the employee actually works.
Choosing an alternative staffing practice means weighing speed, flexibility, cost, control, knowledge retention, and legal risk against the business need.
Alternative Staffing Practices: RPO, Temporary Agencies, Job Sharing & Remote Workers
Quick Answer: Alternative staffing practices meet workforce needs without, or in addition to, permanent full-time on-site hiring. Key options are recruitment process outsourcing (RPO), temporary and agency staffing, temp-to-hire, job sharing, part-time and flexible schedules, remote and hybrid workers, freelancers and contractors, seasonal hiring, and secondments. Each trades some control or cost for speed, flexibility, or access to talent, and each carries its own legal duties.
The aPHRi outline names three examples: recruitment process outsourcing, job sharing, and remote workers. Section 5.4 covers sourcing channels and Employer of Record arrangements; this section compares the full menu of alternatives and the HR controls each needs.
1. Recruitment Process Outsourcing (RPO)
RPO is an arrangement in which an external provider takes over all or part of an employer's recruiting process - sourcing, screening, scheduling interviews, and sometimes offer management - and works under the employer's brand as an extension of its talent acquisition team.
| RPO model | Scope | When it fits |
|---|---|---|
| End-to-end (enterprise) RPO | All or most hiring across the organization | High, continuous hiring volume |
| Project RPO | A defined campaign, such as staffing a new site | Short-term surges with a clear end |
| Selective or modular RPO | Specific steps, such as sourcing or screening only | Internal team is strong but overloaded in one area |
RPO vs. a recruitment agency: an agency usually fills individual vacancies and is paid per placement; an RPO provider manages the recruiting process over time, often with a management fee plus volume-based charges and agreed service levels (for example, time to fill, quality of hire, and candidate satisfaction).
HR's role: define scope and service levels, give the provider accurate job descriptions and requisitions, protect candidate data under a data-processing agreement, monitor fairness and diversity of shortlists, and review performance regularly (Section 4.6 covers vendor management).
2. Temporary and Agency Staffing
A staffing agency recruits workers and assigns them to client organizations. The agency is usually the employer of record for pay, while the client directs the daily work.
- Uses: covering absences, peaks, special projects, or hard-to-fill short-term roles.
- Benefits: speed, flexibility, and the agency handles recruiting and payroll administration.
- Risks: higher hourly cost, lower commitment, knowledge leaving when the assignment ends, and legal duties that remain with the client, especially health and safety and fair treatment.
- Standards: the ILO Private Employment Agencies Convention, 1997 (No. 181) sets principles for agencies, including that they should not charge fees or costs to workers (with limited exceptions) and should respect workers' rights. In the EU, the Temporary Agency Work Directive (2008/104/EC) requires that agency workers' basic working and employment conditions, such as pay and working time, be at least those they would have received if hired directly by the client for the same job.
Temp-to-hire lets both sides try the relationship before a permanent offer. The contract with the agency should state any conversion fee.
3. Job Sharing
In job sharing, two (or occasionally more) employees split one full-time position, dividing hours, duties, pay, and benefits. For example, one person works Monday to Wednesday morning and the other Wednesday afternoon to Friday.
- Benefits: keeps experienced employees who want reduced hours (such as parents, carers, or people nearing retirement), combines complementary skills, and provides built-in cover during absences.
- Challenges: handovers, consistent decision-making, workload balance, and managers' perception of accountability.
- HR controls: a written agreement covering the split of hours and duties, handover routines, what happens if one partner leaves, and pro-rata pay, leave, and benefits.
Job sharing is also a tool to avoid layoffs when work drops, because two jobs can be kept at reduced hours.
4. Remote and Hybrid Workers
Remote workers do their jobs away from the employer's premises, usually from home; hybrid workers split time between home and the workplace. Remote work widens the talent pool and can reduce office costs, but HR must manage:
- Equipment, data security, and privacy (company devices, secure access, clear monitoring notices).
- Health and safety of the home workstation (ergonomic self-assessments).
- Working-time records and the right to disconnect, which some countries now protect by law (Section 10.5).
- Inclusion and communication, so remote staff are not overlooked for development and promotion.
Cross-border remote work
When an employee works remotely from another country, that country's rules may apply to employment protections, income tax withholding, social-security contributions, and immigration. The employer may even create a taxable business presence. Options include hiring through a local entity, using an Employer of Record (Section 5.4), or declining the arrangement. HR should never approve "work from anywhere" without checking these points with legal and tax advisers.
5. Other Alternative Practices
| Practice | Description | Watch-outs |
|---|---|---|
| Freelancers and independent contractors | Self-employed specialists paid for deliverables | Misclassification if they are controlled like employees (Section 3.2) |
| Seasonal hiring | Temporary hires for predictable peaks | Early recruiting, fast onboarding, fixed-term rules |
| Part-time and flexible schedules | Reduced or variable hours for employees | Pro-rata pay and equal treatment |
| Secondment (loan staffing) | An employee works temporarily for another unit or partner organization while keeping the original employer | Written terms on pay, duration, supervision, and return |
| Managed service provider (MSP) with a vendor management system (VMS) | A provider or platform manages many staffing suppliers and contingent workers | Data quality, cost control, and supplier compliance |
| Alumni and retiree pools | Former employees rehired for short projects | Pension and benefit rules for returning retirees |
| Internships and apprenticeships | Structured learning roles | Pay, training, and supervision obligations |
6. Choosing the Right Option
| Business need | Likely fit |
|---|---|
| Hiring 300 people in six months for a new site | Project RPO, plus seasonal or agency staff for the first peak |
| Cover a four-month parental leave | Fixed-term hire or agency temporary |
| Keep a valued specialist who wants three days a week | Job share or part-time arrangement |
| Access a scarce skill in another country without a local entity | Employer of Record or a genuine independent contractor, after legal review |
| Unknown future demand for a new service | Contractors or temp-to-hire before permanent hiring |
A good recommendation explains the trade-offs: speed, flexibility, cost, control, knowledge retention, and legal risk.
A company must hire 250 customer-service staff for a new regional center within five months, but its small recruiting team is already at capacity. Which alternative staffing practice best fits?
Job sharing among existing employees
A project recruitment process outsourcing (RPO) engagement with agreed service levels
Hiring one freelance recruiter on a single placement fee
Pausing recruitment until the internal team is free
Two part-time employees propose to share one full-time training coordinator job. Which HR step is most important before approving the arrangement?
Pay each employee the full-time salary to keep morale high.
Classify both employees as independent contractors.
Put in place a written agreement dividing hours, duties, handovers, and pro-rata pay and benefits, and stating what happens if one partner leaves.
Require both employees to work the same hours every day.
An employee asks to work fully remotely from another country for a year while keeping the same contract. What should HR do?
Review with legal and tax advisers the employment, tax, social-security, and immigration consequences in that country before deciding.
Approve it immediately, because remote work has no legal effects if the contract stays the same.
Change the employee's title to 'contractor' so no rules apply.
Refuse all remote-work requests to avoid any risk.
