HR Assistant Manager (fixed term contract)

We're looking for a positive, proactive, and approachable HR Assistant Manager to join our supportive MAP (Monster Ambition and Progression) team on a 12-month maternity cover contract.

You'll play a key role in supporting managers and employees across a wide range of employee relations matters, helping to create a positive employee experience where people feel supported, valued, and empowered to thrive. This is a fantastic opportunity for someone who enjoys building strong relationships, making a real impact, and contributing to a collaborative and fast-paced environment. There may also be the opportunity to extend the contract depending on business needs and the successful candidate's start date.

Monster Group is one of the UK's fastest-growing e-commerce retailers, supplying high-quality, great-value products to customers around the world. We source directly from suppliers, sell across more than 150 online marketplaces, and deliver directly to our customers from our Monster distribution centres.

At Monster, we do things a little differently. Our values of Fun+, Respect, Empowerment, and Forward-Thinking are at the heart of everything we do and shape the way we work, collaborate, and support one another every day.

Our MAP Team goes beyond traditional HR by championing employee development, progression, wellbeing, and strong working relationships across the business. We're passionate about creating a workplace where our people can grow, succeed, and enjoy coming to work.

Your Role:

• Provide expert advice and guidance to managers on employee relations matters across the business.
• Manage ER cases from start to finish, including investigations, disciplinaries, grievances, and appeals.
• Ensure all ER matters are handled fairly, consistently, and in line with employment legislation and company policies.
• Support managers with short-term absence management, probation reviews, and flexible working requests.
• Coach and upskill managers on MAP policies, procedures, and best practice approaches.
• Support employees and managers with progression planning through Monster Progression Plans (MPPs).
• Collate, analyse, and report on people data, including absence trends and ER metrics.
• Occasionally support with delivering training sessions and workshops on people-related topics and workplace policies.
• Work collaboratively with the wider MAP team to provide a positive employee experience.
• Regular travel to our Scunthorpe sites and occasional travel to our Venlo, Netherlands warehouse will be required to support managers and teams across our wider business operations.

Skills We Love:

• Demonstrable experience providing HR and ER advice within a fast-paced environment.
• Strong knowledge of employee relations processes, policies, and UK employment law.
• Excellent written and verbal communication skills with the ability to influence and support stakeholders at all levels.
• A positive, proactive, and approachable attitude with a genuine passion for supporting people.
• Highly organised with meticulous attention to detail.
• Confident using HR systems and IT packages, including HR reporting tools.
• Ability to manage multiple priorities and maintain confidentiality at all times.
• A solutions-focused mindset with strong problem-solving abilities.
• CIPD Level 5 would be great, but is not essential.
• Knowledge of Dutch employment law would also be advantageous, but not essential.
• Full UK driving licence and willingness to travel between sites.
