Quick Answer
Rehiring a former employee, often termed "boomerang hiring," can reduce ramp-up time and utilize known talent. However, it requires careful evaluation of the employee's original reasons for leaving, their professional growth since departure, and whether their skills align with the company's current strategic needs. Businesses must also consider potential team dynamics and maintain transparent communication regarding updated expectations and compensation to ensure a successful re-integration and prevent costly mistakes.
Companies frequently consider rehiring former employees. This approach, known as "boomerang hiring," can be a strategic move for businesses aiming to utilize the experience and talents of former team members. Even larger organizations like Meta and Salesforce have structured programs for re-engaging alumni. However, before extending an offer to a returning employee, businesses must ask several critical questions.
This post examines the essential considerations businesses should keep in mind when deciding whether to rehire an employee.
Why did the employee leave?
One of the first considerations is the reason for the employee's original departure. Was it due to personal circumstances, a pursuit of a different opportunity, a compensation disagreement, or performance-related issues? Understanding the specific circumstances is crucial, as it directly impacts their potential fit within the current organizational context. An employee who left for personal reasons, such as family care, or for external circumstances unrelated to their work, might be a more suitable rehire than someone whose departure stemmed from internal disagreements or dissatisfaction with their role or management.
For fast-growing seed through Series C startups, particularly those focused on Engineering and AI/ML roles where Recruiting from Scratch specializes, understanding the departure reason is paramount. A misaligned rehire can be costly. Based on 0+ technical hires we've made since 2019, the financial and productivity impact of a poor hiring decision is significant. The average salary for engineers we place is around ~$252K, making each hire a substantial investment. If a past employee left due to a lack of growth opportunities that still persist, or for cultural reasons that haven't changed, rehiring them risks repeating a costly cycle. Evaluating their initial departure reason provides predictive insight into their potential long-term success and satisfaction if rehired.
How have they grown professionally?
Assess the employee's professional development since their departure. Have they acquired new skills, certifications, or experiences that would make them a more valuable asset to your company today? Or, conversely, are they now working in an industry or role that is significantly different from your company's core operations or technological stack? Consider how their evolution aligns with your current business needs, especially for highly specialized technical roles.
For startups operating in competitive sectors like AI/ML, the pace of technological change is rapid. An engineer who left three years ago might have valuable foundational knowledge, but their subsequent professional growth must align with current demands. We've placed engineers at 549+ startups, observing firsthand that the most successful candidates continually adapt and acquire skills relevant to areas such as machine learning frameworks, cloud infrastructure, or specific programming languages crucial for deep tech roles. If a former employee has expanded their expertise in these areas, they could bring immediate value. If their growth has diverged significantly, the ramp-up time might be similar to, or even longer than, a new external hire, negating one of the primary benefits of boomerang hiring.
Am I considering rehiring them because they’re a familiar face?
Rehiring an employee means reintroducing someone already familiar with your company's culture, processes, and team dynamics. This familiarity can be appealing, as training new hires and integrating them into operations can be time-consuming and often presents unforeseen challenges. In our data, the average time to fill a technical role is 29 days, but the onboarding process extends well beyond this, requiring significant internal resources.
However, before making a rehiring decision, critically assess whether the primary motivation is a quick fix or if the individual genuinely brings a skillset or fills a critical function that the company needs. For a technical hire with an average salary of ~$252K, a decision driven solely by familiarity rather than genuine need can become a significant financial and productivity drain if the fit is not precise. While familiarity can reduce the initial ramp-up, a lack of true necessity for their specific skills can result in underutilization or, worse, another eventual separation. The goal should always be to secure talent that contributes directly to the company's strategic objectives, not simply to fill a role expediently with a known quantity.
How well would they work with others on the team?
Consider gathering input from colleagues and team members who previously worked alongside the returning employee. Their insights can provide valuable perspectives on how the individual might integrate into the current team dynamics. This feedback can also offer insights into why they left in the first place, if you were unsure, by revealing past interpersonal challenges or unaddressed conflicts.
It is important to acknowledge that rehiring an employee may cause unease among certain existing team members, particularly if there were past issues or if the returning employee is placed in a managerial role above former peers. A shift in team hierarchy or dynamics can disrupt established working relationships and potentially lead to dissatisfaction among existing employees, which can impact morale and even lead to further departures. Given the difficulty of attracting and retaining top technical talent in the startup ecosystem where Recruiting from Scratch operates, maintaining a cohesive and positive team environment is paramount. A rehiring decision should not inadvertently destabilize the team you have built.
Are they truly needed?
Consider whether the specific skills and expertise of the returning employee are a precise fit for your company's current needs and strategic objectives. Your organization has likely evolved since their departure, and it is essential to determine if they can genuinely contribute to your current goals. For seed through Series C startups, especially those specializing in Engineering and AI/ML roles, every hire must directly support critical initiatives.
It is possible that a former employee would be a welcome fit back on the team and could significantly benefit the company with their skills. However, it is also possible that you have successfully managed many aspects of their old role without them, or that the responsibilities they previously held have shifted or been absorbed by others. The skills gap they once filled may no longer exist. In some cases, bringing them back on a consulting or part-time basis might be a prudent step to assess the fit before committing to a full-time role.
Even though it can be a difficult decision, if their skills are no longer truly needed, it is best for both parties to move forward separately. Rehiring someone only to find they are not essential can lead to another departure within a few months. The financial implications of a failed hire are substantial, considering an average engineer salary of ~$252K and the associated recruiting fees, which typically range from 25-30% of the first-year base salary when engaging an external firm. Avoiding a misaligned rehire protects both the company's financial resources and the individual's career trajectory.
Do they know what to expect if they come back?
Maintain open and transparent communication throughout the entire rehiring process. Discuss expectations clearly, both from the company's perspective and that of the returning employee. Be explicit about any changes or developments that have occurred since their departure. Former employees may assume that everything remains the same when they rejoin, but it is crucial to clarify new managerial structures, shifts in company culture, updates to compensation and benefits packages, or changes in specific role responsibilities.
For instance, a company that was a seed-stage startup in 2019 when Recruiting from Scratch was founded might now be a Series C firm with 549+ active startup clients, operating with different internal processes and expectations. Compensation structures, especially for technical roles with an average salary of ~$252K, may have evolved significantly to align with market rates and performance incentives. A lack of transparency regarding these changes can lead to dissatisfaction and a renewed desire to leave shortly after rejoining. Clear communication ensures that the returning employee has a realistic understanding of their role, their team, and the company's current direction, setting the foundation for a successful and lasting re-engagement.
