If a promotion letter conflicts with an existing employment contract, identify what was actually proposed and agreed. Do not assume every old term disappeared or every new HR-system entry became binding.

Review the documents with the employee and obtain legal advice where the contractual position is uncertain.
Compare the changed terms
Check role, duties, salary, working arrangements, benefits, notice and any additional obligations. Identify the effective date and whether the letter says other terms continue.
MOM’s guidance states that employers cannot change contract terms without employee consent and recommends clearly documenting agreed new terms.
Example: the HR system shows a longer notice period
The promotion letter changes the title and pay, but the HR database also increases notice. Establish the source of that change and whether it was actually agreed. A system setting is not a substitute for the contract review.
Prepare the reconciliation pack
- Original contract and relevant policies.
- Promotion proposal and signed documents.
- Correspondence about negotiated changes.
- Payroll and HR settings from the effective date.
- Any work-pass or reporting implications.
- Unresolved points requiring agreement or advice.
Keep a clear distinction between acknowledging receipt and agreeing to a proposed variation where that matters on the facts.
Document the resolved position
Use an appropriately drafted document explaining which terms change and which continue. Avoid silently substituting a new contract version in the folder.
If the parties disagree, seek advice on the actual options and applicable obligations. Do not use a disputed variation as a reason for an unrelated salary deduction.
Update linked systems accurately
Once the position is established, align payroll, benefits, reporting lines and relevant official records. Retain the genuine agreement and effective-date evidence.
Review the next payslip and HR output to ensure the implementation matches what was agreed.
Does a promotion automatically change the notice period?
Check the agreed terms and applicable law.
Can HR software settle a contractual disagreement?
No. Resolve the underlying position first.
