We’re looking for an experienced trade union organiser to lead campaigns, grow our membership, support activists and deliver outstanding representation.

The role

Our 1,200 staff work across 12 UK regions and our national centre in London.

As a Regional Organiser, you’ll be playing a hands on, day to day leadership role, as well as acting as an advocate of the union. Guiding, supporting and developing local branches and activists to ensure the strongest possible workplace organisation, you’ll identify activist training and development needs, provide coaching and mentoring to stewards and branch officers, and manage a small team of area/local organisers. Additionally, you will lead negotiations, represent members individually and collectively, and help branches to develop effective systems and processes for handling casework.

The person

• An understanding of our movement, its pressures and drivers, with a passion for equality.

• Good knowledge of key employment law, including developing case law and upcoming changes that may affect members.

• Good understanding of the political landscape and how this might impact our approach.

• Ability to manage a team of staff, with a willingness to collaborate and to lead by example.

• Excellent communication and advocacy skills, with proven ability to manage high level negotiations and representation of cases in challenging situations.

• Ability to build and strengthen relationships with key stakeholders, ability to influence and engage at all levels eg activists, democratic bodies/committees.

• Strategic project management experience, including budget management. Ability to develop strategies and solutions to solve complex problems.

This is a field based role and you will need to be able to travel in and around the South West region, including to our regional offices in Bristol, Exeter, Taunton and Poole, as required and occasionally to London for training, meetings or other purposes. The South West region covers a large area from Wiltshire to Cornwall.  However, for the foreseeable future we expect this post to be based in the Bristol office and will be supporting our branches in the north of the region (Bristol, Bath, South Gloucestershire, North Somerset, Wiltshire and Gloucestershire).
