Narrowest Skill Band in India — ₹65/day Gap
Sikkim has the tightest skill wage structure — lowest misclassification incentive.
| Skill Level | MW (₹/mo) | Daily Rate (₹/22 days) | Bonus Diff from Unskilled (₹/yr) |
|---|---|---|---|
| Unskilled | ₹13,000 | ₹591 | — |

| Delhi | ₹157/day | 25% | High |

- Most skill disputes arise from ambiguous role descriptions, not pure bonus gaming

Disclaimer
Bonus calculations based on the Payment of Bonus Act, 1965 (as amended 2015) and Sikkim minimum wages with altitude-based premiums. Altitude classification must be verified independently — elevation affects both bonus eligibility and PT liability. Workers at 12,000+ ft exceed ₹21,000 ceiling and are ineligible. The ₹7,000 statutory floor is overridden by the higher Sikkim minimum wage in all categories. Bonus must be paid by November 30. This guide does not constitute legal or financial advice — consult a qualified labour law professional for compliance in specific scenarios, particularly for multi-altitude employers.
