Why Greencore? 

We’re one of the UK’s leading creators of convenience food, driven by a simple purpose: to make everyday taste better. 

As a vibrant and fast-moving business, we’re proud to employ over 13,300 talented colleagues across 16 manufacturing sites and 17 distribution depots throughout the UK. Together, we bring delicious food to life, from sandwiches, and sushi to cooking sauces, pickles, and ready meals. In FY25, our shared passion helped us achieve revenues of £1.95bn. 

We’re looking for a people-focused HR Advisor to join our site HR team at Manton Wood on a permanent basis, supporting one of our busiest and most dynamic manufacturing environments.  

Please note: This is a site-based role requiring you to be present on-site five days a week at Manton Wood. The role is full time, Monday to Friday, with regular late shifts required to interface with our night shift and 24/7 operation. 

What you’ll be doing 

As HR Advisor, you’ll deliver a proactive, professional and people-focused HR service that supports line managers and colleagues through the full range of employee relations activity on site. 

You will: 

• Provide timely, practical advice and guidance to line managers on a wide range of ER issues, from day-to-day people queries through to more complex casework 
• Manage a high-volume ER caseload, ensuring issues are progressed promptly, fairly and in line with Greencore policy, process and employment law 
• Support formal meetings and hearings (investigations, disciplinaries, grievances, performance and absence) including preparation of documentation and note-taking where required 
• Help maintain positive relationships with site trade union / colleague representatives, supporting collective consultation and local agreements 
• Build strong, trusted relationships with stakeholders across the site—from production and operational leaders to support functions and senior managers 
• Analyse ER and absence data and contribute to site-wide plans and projects that improve engagement, attendance and colleague experience 
• Support HR cycles and activity such as probation, performance, talent and succession, ensuring managers are confident and equipped to lead their teams 
• Flex your working hours to align with operational needs, including regular late shifts and occasional early/night-shift meetings to maintain visibility and support across all shifts 

What we’re looking for 

• Strong experience in an HR role with a clear focus on employee relations, ideally within a fast-paced, operational or manufacturing environment 
• Proven ability to manage a high-volume ER caseload, balancing pace with accuracy, fairness and good judgement 
• Confidence to coach, influence and when needed, challenge line managers and stakeholders in a unionised setting 
• Strong knowledge of core employment law principles and HR best practice, with the ability to translate these into practical, site-friendly guidance 
• A clear, calm and professional communicator—comfortable handling difficult conversations and sensitive issues 
• Highly organised and resilient, able to prioritise and stay focused in a demanding, 24/7, production-led environment 
• CIPD part-qualified or working towards CIPD (or equivalent experience). 

At Greencore we put our people at the core. We celebrate their differences and help everyone to be themselves at work. Together we make every day taste better.  

What you’ll get in return 

• Competitive salary and benefits 
• 25 days holiday plus bank holidays 
• Pension up to 8% matched 
• Life insurance up to 4x salary 
• Company share save scheme
