How to say “Politically express unwillingness to work” professionally

Level 1: Thank you for considering me for this project. Given my current commitments and the critical path items I am currently driving, taking on this additional responsibility at this time would risk diluting focus from our core objectives. Could we explore re-prioritizing existing tasks or perhaps identifying another colleague who might have more bandwidth?

Level 2: I appreciate the opportunity. To ensure all current projects maintain their projected timelines, I would need a clear understanding of which existing priorities should be de-prioritized to accommodate this new initiative. Could you provide guidance on the strategic trade-offs required?

Level 3: Per our recent workload management audit and the Q3 capacity planning documentation, my current bandwidth is fully allocated to initiatives directly supporting [specific company KPI]. While I understand the urgent nature of this 'new' request, perhaps we should revisit the project's RACI matrix and resource allocation strategy before committing further.

Level 4: I cannot take on this additional task without compromising the quality and timelines of my current, high-priority projects. If this is a critical initiative, we need to formally re-evaluate my current assignments and adjust expectations accordingly.

Level 5: Not my problem.

Level 1: We understand your request. However, this falls outside the parameters of our current Statement of Work. To incorporate this, we would need to initiate a formal change request process to assess scope, timeline, and associated costs.

Level 2: Thank you for sharing your vision. While this direction is intriguing, it represents a significant deviation from our agreed-upon project plan and deliverables. We would need to re-evaluate the project's foundational objectives to proceed.

Level 3: Per the signed Master Services Agreement, Section 3.2, 'Scope of Deliverables,' this request appears to introduce new requirements not previously detailed in Appendix A, 'Project Scope.' We are, of course, happy to discuss a new engagement under separate terms.

Level 4: This specific request is beyond the scope of our current contract and cannot be accommodated under the existing terms. If you wish to pursue this, we will need to formalize a new agreement and revised project plan.

Level 5: Read the contract.

Level 1: Thanks for reaching out. My current project load is at capacity right now, so I won't be able to take this on. Is there someone else on the team with the relevant expertise who might have the bandwidth?

Level 2: I appreciate you thinking of me for this. To maintain focus on my current deliverables, I'm unable to commit to additional tasks at this moment. Have you checked the team's shared workload tracker to see who might be available?

Level 3: That's a fascinating interpretation of 'team collaboration.' While I'm deeply committed to collective success, my deliverables per the Q4 sprint plan are already at 100% capacity. Perhaps you could consult the project's RACI or your own job description for clarification.

Level 4: I am not able to do this task for you. My current responsibilities require my full attention, and taking this on would put my own deadlines at risk. You'll need to find another solution.

Level 5: No.
