Notice period:
Singapore vs United States

Statutory notice period in Singapore and the US, side by side, with the primary source for every figure.

How do notice periods compare between Singapore and US?

Singapore: Where the contract is silent: 1 day to 4 weeks by length of service. The contract can set any period, as long as it is the same both ways. United States: None. Employment is at-will; the only federal notice rule is the WARN Act's 60 days for qualifying mass layoffs.

Singapore

Singapore's Employment Act scale is a fallback, not a floor. If the contract sets notice, that applies (it must be equal for employer and employee). If it does not, the statutory bands run from 1 day under 26 weeks' service to 4 weeks at 5 years or more. Either side can pay salary in lieu.

  • Default range1 day to 4 weeks by tenure
  • Contractual noticeOverrides the default; must be equal both ways
  • Payment in lieuPermitted
Length of serviceEntitlement
Less than 26 weeks1 day
26 weeks to under 2 years1 week
2 to under 5 years2 weeks
5 years or more4 weeks
  • Because the scale is only a fallback, a contract can lawfully set shorter notice than the default bands.

United States

No US federal law requires notice for an individual dismissal. The WARN Act requires 60 calendar days' written notice, but only for plant closings and mass layoffs at employers with 100 or more employees, and several states run stricter mini-WARN versions. Individual notice, where it exists, comes from the contract.

  • Individual dismissalNo federal notice requirement
  • WARN Act60 days, mass layoffs at 100+ employee firms
  • State variationMini-WARN laws in several states
  • Montana is the main exception to pure at-will employment.
  • Failing to give WARN notice costs up to 60 days' back pay and benefits per employee.

The rules you can look up.
The people you cannot.

Compono is a talent intelligence platform: an applicant tracking system and an employee engagement platform built on the same people data.

Comparing entitlements is the easy half of hiring across markets. The hard half is whether the person you hire in Sydney, Singapore or Seattle will actually work out, and that risk looks the same in every jurisdiction. Compono matches candidates on how they work as well as what the CV claims, so the hires behind these numbers hold up wherever you make them.
