FAQ

How is Senta different from a traditional HR consulting firm?

Senta brings both senior HR leadership combined with hands-on execution. Our work is not limited to recommendations. We partner with clients to diagnose, built, implement, and sustain the work over time.

Does Senta outsource my full HR function?

No. Senta works in partnership with clients, providing tailored HR support based on what the organization actually needs. That may include fractional leadership, interim support, project-based work, or strategic guidance, either alongside an internal HR or leadership team or in support of a specific gap. Our work is strongest when there are internal stakeholders who can help own and carry the work forward. We are not a Professional Employer Organization (PEO) or an Employer of Record (EOR).

Can Senta work alongside an internal HR team?

Yes. In many cases, that is our preference. Senta can step in as an extension of an existing HR team, provide senior-level support where it is needed, or help stabilize work that internal teams do not currently have the capacity or structure to carry through.

How quickly can Senta step in?

Timing depends on scope and current availability. As a boutique firm, we take on work selectively and may sometimes need to schedule engagements into the future. Availability and timing can be discussed in an initial consultation, and if the need is urgent, we encourage you to reach out and ask.

What should we expect from an initial conversation?

An initial conversation is focused on understanding the current situation, where support is needed most, sharing more about Senta and our model, and determining whether there is a strong fit between the business need and the support we provide.

What is the difference between fractional, interim, advisory, and project-based support?

Fractional support provides ongoing senior HR leadership on a part-time basis. Interim support fills a leadership or capability gap for a defined period, either part-time or full-time. Advisory support helps leaders navigate important people decisions while retaining execution internally. Project-based support is built around a specific priority, with a defined scope, timeline, and set of deliverables.

Who leads the work?

Client work is led directly by Angela Hayes, Co-Founder and Fractional CHRO, with support from a trusted network of experienced HR practitioners brought in selectively based on the needs of the engagement.

Do you have expertise in California?

Yes. Senta is based in California and has deep experience navigating the state’s unique labor market and employment landscape. While we support clients across the United States, California is our area of deepest expertise.

Do you help with recruiting?

Yes. Recruitment is one of our project-based offerings, and we support recruiting on a retained search model. Most often, we do this for clients already in our network and receiving other HR support from us, which gives us a stronger understanding of the organization, the role, and the kind of candidate most likely to succeed. We can support recruiting on a one-off basis, but that work requires time upfront to understand the organization, the hiring managers, and what success in the role should look like.

Do you conduct employee investigations?

No. We do not offer employee investigations as a service. We can help internal teams manage their own process and, when appropriate, recommend qualified outside partners.

Does Senta offer payroll and/or benefits support?

Senta can support wage and hour reviews, policy development, and strategic benefits guidance. We are not a payroll processor or benefits administration provider. When payroll or benefits issues are part of a broader HR challenge, we can help assess the issue and recommend an outside provider.

Does Senta help with employee handbooks and HR policies?

Yes. Senta helps organizations strengthen the HR foundations that support clearer guidance, more consistent decision-making, and better day-to-day people practices, including handbooks, policies, and related HR documentation.
