The most effective way to increase participation in a 401(k) plan is to implement automatic plan enrollment (C) . SPHR-level benefits strategy recognizes that employee participation is heavily influenced by behavioral factors, particularly inertia and decision avoidance.

Automatic enrollment shifts the default choice from “opt in” to “opt out,” significantly increasing participation rates without requiring active employee decision-making. Numerous workforce studies and benefits best practices demonstrate that automatic enrollment leads to substantial and sustained increases in plan participation across demographic groups.

While reducing fees (A) and shortening vesting periods (B) may improve plan attractiveness, they do not address the primary barrier to participation—failure to take action. Increasing fund options (D) can actually decrease participation by overwhelming employees with choices.

SPHR exam content emphasizes that effective benefits design leverages behavioral economics to drive desired outcomes. Automatic enrollment is considered a best practice for retirement readiness and aligns with fiduciary responsibility to support employees’ long-term financial well-being.

Comprehensive and Detailed Explanation:

After a merger, alignment around shared team goals builds cohesion. Without unified direction, cultural clashes and productivity dips are common.

SPHR-aligned strategy emphasizes goal integration to unify processes, performance, and culture in post-merger transitions.

Comprehensive and Detailed Explanation:

High-risk employees (e.g., those with chronic conditions or unhealthy lifestyles) drive the majority of healthcare costs . Engaging them leads to the biggest cost reductions and improved long-term health outcomes.

SPHR-aligned engagement strategies support targeted wellness participation and incentives for at-risk populations as key ROI drivers in cost management programs.

The talent management process (C) is central to aligning HR strategy with business goals. This includes workforce planning, recruitment, development, performance, and succession — all of which must support organizational objectives .

Extract from HRCI-aligned HR knowledge : The Leadership and Strategy domain states that strategic HR requires aligning talent management infrastructure with business drivers , ensuring that HR practices are not isolated , but integrated with core organizational strategy .

During a merger, HR is strategically involved by performing due diligence (C) . At the SPHR level, HR due diligence is critical to identifying people-related risks, liabilities, and integration challenges that directly affect deal value.

HR due diligence includes assessing workforce demographics, compensation and benefits obligations, labor relations issues, leadership capability, culture, compliance risks, and talent retention concerns. These insights inform integration planning and executive decision-making.

Assessing strategic fit (B) is primarily an executive responsibility. Reviewing contracts (A) and legal compliance (D) are important but more tactical.

SPHR exam content highlights HR due diligence as a core strategic contribution in mergers and acquisitions.

Earnings Per Share (EPS) = Net Income ÷ Number of Outstanding Shares

= $50 million ÷ 10 million shares

= $5 per share

Extract from HRCI-aligned HR knowledge : In the Leadership and Strategy domain, SPHR candidates are expected to understand key financial metrics like EPS, which is a standard measure of organizational profitability . Mastery of such indicators supports strategic alignment between HR and finance .

A. Communicate clear expectations is the best answer because successful return-to-work reintegration depends on employees and managers understanding the employee ' s role, responsibilities, schedule, workplace changes, available support, applicable restrictions or accommodations, and the expectations associated with the return.

Within the requested HRCI framework, this question fits most closely with Employee Relations and Engagement , which requires knowledge of positive employee-relations strategies, human-relations concepts, performance management, employee satisfaction, and effective workplace practices. Clear communication supports each of these areas by reducing uncertainty and helping the returning employee and supervisor coordinate an effective transition.

Return-to-work guidance from the U.S. Department of Labor emphasizes clearly identifying and communicating the roles and responsibilities of employees, supervisors, HR or return-to-work coordinators, and other involved parties. Its guidance specifically explains that clarifying responsibilities establishes accountability and supports successful return-to-work outcomes.

B. Reduce workload demands is not automatically appropriate. Some returning employees may require temporary adjustments or reasonable accommodations, but HR should not assume that every individual returning from extended leave needs reduced responsibilities. Adjustments should be based on the circumstances and, where relevant, an individualized accommodation process.

C. Conduct fitness-for-duty tests is too broad. Depending on the leave and applicable requirements, an employer may sometimes require appropriate return-to-work or fitness-for-duty documentation. However, this is not a universal reintegration strategy, and medical inquiries or examinations must be handled carefully under applicable requirements.

D. Establish a 60-day check-in plan can be useful as one follow-up mechanism, but an arbitrary 60-day interval is not the most important first practice. Effective reintegration requires communication before and at the point of return, with follow-up adjusted to individual needs.

The SPHR-level principle is to establish clarity rather than make assumptions. HR should coordinate expectations, responsibilities, support, and communication so that the employee can resume work effectively. Thus, A is the strongest answer.

Organizations commonly introduce gainsharing following a merger to increase organizational productivity (B) and link organizational and employee goals (E) . At the SPHR level, gainsharing is recognized as a group-based incentive plan designed to improve performance by rewarding employees for collective improvements in efficiency, quality, or cost control.

Following a merger, organizations often face integration challenges such as inconsistent processes, cultural differences, and misaligned incentives. Gainsharing encourages collaboration across legacy groups by focusing employees on shared operational goals rather than individual performance. By tying rewards to measurable improvements in organizational outcomes, gainsharing reinforces teamwork and collective accountability.

Increasing productivity is a primary driver because gainsharing incentivizes employees to identify efficiencies, reduce waste, and improve processes during a period of change. Linking organizational and employee goals helps unify the workforce around common success measures, which is especially critical after a merger.

Aligning pay with individual performance (C) is characteristic of merit or incentive pay, not gainsharing. Addressing pay discrepancies (D) is typically handled through job evaluation or market adjustments. Reducing training needs (A) is not a direct objective of gainsharing.

SPHR exam content emphasizes that gainsharing is most effective when organizations seek post-merger integration, productivity gains, and alignment of collective effort with business results .

To achieve desired results after an acquisition, management must ensure that the strengths of the combined organizations are realized (D) . At the SPHR level, post-acquisition success depends on integration effectiveness , not just transaction execution.

While due diligence (A) and legal expertise (B) are critical before and during the deal, they do not guarantee value creation. Realizing combined strengths—such as complementary capabilities, talent, market access, and operational synergies—is what ultimately delivers strategic benefit.

Third-party investment (C) may support financing but does not drive integration success.

SPHR exam content emphasizes that HR plays a key role in identifying, retaining, and integrating talent to ensure that the human capital synergies envisioned in the acquisition are actually achieved.

C. Providing transparent policies is the best answer because the question asks what establishes trust , not simply which technical control protects information. Trust develops when employees understand what personal information the organization collects, why it collects it, how the information will be used, who may access it, how it is protected, and what standards govern retention and disclosure.

The HRCI SPHR Exam Content Outline places this subject within Employee Relations and Engagement under the five-domain framework requested here. HRCI specifically includes “data security/privacy” among employee security strategies and lists “Data security and privacy” as a required knowledge area. The current SPHR framework likewise requires alignment of HR data-privacy and security processes with organizational data-protection strategies.

Transparency is especially relevant to the wording “establishes trust.” NIST ' s analysis of privacy-framework input identifies a strong relationship among transparency, accountability, privacy practices, and improved trust. It notes that transparent, documented policies help individuals understand organizational responsibilities and hold organizations accountable for data practices. The FTC likewise emphasizes clear disclosure regarding data collection, use, confidentiality, and protection as an important privacy principle.

A. Securing storage systems is essential for actually protecting information, but employees cannot infer the organization ' s entire privacy approach from storage controls alone.

B. Implementing collection methods addresses how information enters the system but does not demonstrate why data is collected, how it is used, or how privacy is maintained.

D. Incorporating biometric protocols for access can strengthen authentication, but biometrics themselves create additional sensitive-data considerations. They are a specific security technique rather than the foundation for privacy trust.

A mature privacy program requires both substantive safeguards and transparency . Among these answer choices, however, transparent policies most directly establish confidence by making organizational privacy commitments understandable and accountable. Therefore, C is the best SPHR-style response.
