ISS: End-to-end strategic resourcing partnership

The Challenge

Previously, ISS relied on over 120 agencies to source 50% of candidates at substantial cost; this was unsustainable. ISS required a dedicated recruitment team with expertise in high-volume hiring and employer brand development across 13 business units.

Key drivers included:

  • Better visibility and control through technology
  • Access to quality talent and sustainable talent pools
  • Reduced agency reliance and costs

The Solution

Omni provided a tailored in-house team for ISS and implemented efficient resourcing processes. Together with ISS’s team, Omni developed an industry-leading Employer Value Proposition to attract top talent.

Omni’s solutions so far include:

  • A proprietary applicant tracking system for efficiency
  • Employer brand strategy and content to engage candidates
  • Talent pool creation for key roles
  • Hands-on interview and assessment support

Partnership

By partnering with Omni, ISS transformed recruitment through strategic solutions that delivered control, efficiency, and access to talent. Omni’s expertise in high-volume hiring, employer branding, and technology helped to transform ISS’s recruitment capabilities.

“I’ve worked with Omni on a number of recruitment and talent searches in the last few months, and found the attention to detail, focus on partnering to find the right candidates, and communication throughout each and every stage of the process to be excellent. Omni understands the business unit’s needs and works diligently to shortlist appropriate candidates. The post placement follow up is equally appreciated and adds value both for the employing manager and the successful candidate.” Benn Knapp, Key Account Director, EY UK & Ireland at ISS Facility Services UK
