Flex and Remote as Package Items

The salary offer is stuck and honestly you care more about not commuting five days a week anyway. This scripts the negotiation: how to put flexible and remote working on the table as real, costed package items, so you trade for what you actually want without torching the offer.

I'm negotiating a job offer where the salary ({OFFERED_SALARY}) is close to what I want but not quite there. Rather than push hard on pay, I want to negotiate flexibility into the package: specifically {FLEXIBILITY_ASK}. The company's current stated policy is {COMPANY_POLICY}.

Write me scripts for the following:
1. Framing flexibility as a productivity and retention benefit for them, not a lifestyle preference for me
2. Proposing a trial period if they're hesitant
3. Assigning a monetary value to the flexibility I'm asking for, so I can present it as equivalent to a salary uplift
4. Handling pushback if they say the role requires in-person presence

Include the specific phrases that make this land as professional rather than entitled.
