Case Study: Adecco

About Adecco

Adecco is a global leader in workforce solutions, connecting thousands of talented individuals with opportunities across temporary staffing, permanent placement, career transition, and talent development. For one of their key clients, Tesco Locums, Adecco required a robust and scalable solution to manage the onboarding and compliance of more than 5,000 locum pharmacists.

The challenge

Managing such a large volume of locums brought significant compliance and operational challenges. Adecco needed a solution that would:

• Validate all locums against the General Pharmaceutical Council (GPhC) register, instantly flagging any that were not on their approved list of pharmacists and block them from registration.
• Capture critical data such as bank details and NHS Smart Card numbers during onboarding.
• Allow locums to upload Right to Work documents, DBS certificates, and other compliance evidence for review and verification.
• Streamline the placement process with online offer and acceptance functionality.
• Enable locums to select pharmacy locations that are accessible to them.
• Ensure IR35 compliance for all assignments.
• Fully integrate with both Adecco and Tesco Locums’ workforce management systems.

The system had to be quick to implement, audit-ready and able to scale without adding significant administrative overheads.

The solution

Giant worked closely with Adecco to deliver a bespoke onboarding and compliance portal, tailored to their exact needs. The solution included:

• Automated GPhC validation to ensure only registered, compliant locums could progress to onboarding
• Customised onboarding journeys with interrupt screens to capture essential data.
• Document upload and verification workflows to simplify compliance checks and reduce risk.
• Placement management tools for online offers and acceptance, improving efficiency for both Adecco and the locums.
• IR35 status assessments to ensure tax compliance and protect against HMRC penalties.
• Customised Reporting to support with Adecco’s management information requirements.
• System integrations with Adecco and Tesco Locums’ platforms through bespoke data import and export routines.

The portal was delivered within six weeks, driven by twice-weekly project calls and hyper-care support following go-live to ensure a smooth transition.

The results

The partnership between Adecco and Giant delivered many measurable benefits:

• Automated GPhC validation removed the risk of non-compliant placements.
• Tailored workflows and automation enabled high-volume onboarding with consistent quality.
• A single secure portal improved data security compared to fragmented email/document exchanges.
• Guided onboarding gave locums a clearer, faster experience, making compliance easier to achieve.
• Audit-ready records provided Adecco with full visibility and confidence in compliance.
• The scalable design ensured the system could manage 5,000+ records without proportional increases in admin resources.
• Seamless reporting through data replication, maintained Adecco’s internal insight requirements.

A few thoughts

“The solution we deliver to Tesco in the Pharmaceutical field is unique, rendering standard off-the-shelf technologies insufficient to meet their distinct operational requirements. Giant demonstrated a deep understanding of both our needs and those of our client, working closely with us to co-create a bespoke offering tailored to these specific demands. From initial design through to implementation, the project was successfully delivered within four months, with no disruption to client services. This outcome was only achievable through the strength of our collaboration and shared commitment to excellence.”
