Casework is at the heart of everything Medical Justice does. We assist vulnerable people in immigration detention to access medical evidence. The evidence we produce forms the basis of our advocacy work to secure lasting change, including our research into the systemic failures in safeguarding and healthcare provision, the harm caused by these shortcomings, and the harmful effect of immigration detention itself on the health of those who are subjected to it.
As a Caseworker you will have your own caseload and be working directly with people in immigration detention, many of whom may be very unwell, traumatised and experiencing deterioration in their health. You will coordinate with our clinicians and, if clients have legal representation, their lawyers, to organise medical assessments. You will maintain communication with your clients throughout this process, acting as a key point of contact.
We are looking for an experienced caseworker, who can use their compassion and organisational skills to support clients in extremely vulnerable situations. We are looking for someone who has experience dealing with clients in crisis situations, who is resilient and able to manage complex, often traumatic, caseloads in a professional and empathetic way. You will play a key role in striving to ensure clients receive access to adequate healthcare and that they obtain high-quality independent medical evidence to progress their legal cases. As well as working as part of a small, dedicated team of caseworkers dealing with around 500 referrals a year.
Location: North London, the role is hybrid with 3 days based in the office each week following the successful completion of probation and training period.
