Design a Boundary for a Draining Work Relationship

A colleague interrupts constantly, expects replies at midnight, or quietly loads work onto you, and you have said nothing because conflict feels worse than coping. This designs a boundary you can actually hold given the power balance: what to say, when, and how to keep it once you have. Good for anyone worn down by someone they cannot just avoid.

<context>
You have a colleague, manager, or client described as {DRAINING_RELATIONSHIP} whose behaviour is [describe: e.g. constantly interrupting / demanding immediate responses outside hours / taking credit for your work / loading you with tasks informally]. You have not addressed it directly because [fear of conflict / power imbalance / uncertain if it is reasonable to object].
</context>

<task>
**Design and implement a practical boundary:**
1. Assess whether this is a boundaries problem, a communication problem, or a culture problem: they require different responses
2. Define the specific behaviour you want to change (not the person, the pattern)
3. Write a direct but professional statement of the boundary: what you will and will not do
4. Anticipate the likely reaction and prepare a response that holds the boundary without escalating
5. Define a review point: how will you know in 4 weeks if it is working?
</task>

<output_format>
- Problem type assessment (boundary / communication / culture, with reasoning)
- Specific behaviour defined (one sentence, observable and neutral)
- Boundary statement (verbatim, professional tone)
- Likely reaction + response (one scenario prepared)
- 4-week review signal (one observable indicator)
