Ten perks with real productivity effect.

1. Flexible hours
2. Remote-work option
3. Quality office chairs and monitors
4. Quiet focus space
5. Genuine paid time off (and taking it)
6. Good health insurance (reduces stress)
7. Mental health support
8. Learning / education stipends
9. Gym or fitness reimbursement
10. Catered lunch or food credits (removes decision fatigue)

The perks that actually matter reduce friction and protect energy; novelty perks rarely do either.
