Design a volunteer role, recruitment post, and onboarding plan

Help me design a volunteer role for my nonprofit. The work: [what needs doing and why it matters to the mission] Time commitment: [hours, schedule, minimum term] Skills or requirements: [e.g. lifting, a language, a car, comfort with teens] Who they will work with: [vulnerable groups such as children or older adults? unsupervised?] Supervisor: [ROLE] What we can offer volunteers: [training, references, community, flexibility] Give me: 1. A volunteer position description: purpose, responsibilities, time, qualifications, training, supervisor, and benefits to the volunteer. 2. A recruitment post (about 120 words) and a 2-sentence version for social media, written around the impact and the volunteer's motivations. 3. A screening plan proportionate to risk: application, conversation, references, and background checks where the role involves vulnerable people, following our policies and local law. 4. An onboarding plan: orientation agenda, role training, safeguarding and confidentiality, and the first shift with a buddy. 5. Retention: check-ins at 30 and 90 days, recognition ideas, and how to track hours and feedback. 6. Boundaries: what volunteers should not do (e.g. replace paid staff duties, handle confidential records without training) and how to raise concerns. Note any employment-law issues to check, such as volunteers who are also employees or interns, and confirm insurance coverage for volunteers.
