Businesses change. A role grows, a team merges, a budget shrinks. Sooner or later you will want to change the terms of someone’s contract, and in the UAE the law is clear about who decides: both of you.
In July 2026, MOHRE restated the rule plainly. An employer cannot change an employee’s salary, job title or the nature of their work without the employee’s explicit written consent. Any clause that cuts an employee’s rights below the legal minimum is void, unless the change works in the employee’s favour.
None of this is new law. It comes from Federal Decree-Law No. 33 of 2021, the UAE’s labour law. But MOHRE chose to say it again, and that is usually a sign it has seen too many employers get it wrong.
What the law says
Three parts of the law do most of the work.
Article 12 says you cannot assign an employee work that is substantially different from what they agreed to. There is an exception: if the work is necessary, or prevents or repairs an accident, you may assign it temporarily, for the period the Executive Regulations allow. Anything beyond that needs the employee’s written consent.
Article 14 says you cannot use any means to force an employee to work, or threaten them into it.
Article 45 gives the employee an exit. If you assign substantially different work without written consent, outside the exceptions in Article 12, the employee may leave without notice and keep all their end-of-service entitlements.
Read together, these say: a contract is an agreement, and you cannot rewrite one side of it alone.
Which changes need what
| Change | Employee’s written consent | Record it with MOHRE |
|---|---|---|
| Lower salary, or a lower basic salary within the same total | Yes, explicit and in writing | Yes |
| New job title | Yes | Yes; the title on the work permit must match |
| Substantially different work | Yes, unless temporary and necessary under Article 12 | Yes, if permanent |
| Pay rise or better benefits | Put it in writing anyway | Yes; the registered contract should match what you pay |
The second line catches people out. Moving money from basic salary into allowances leaves take-home pay unchanged, so it can look harmless. It is not. End-of-service gratuity is calculated on basic salary: 21 days’ basic pay for each of the first five years, 30 days for each year after. Cut the basic and you cut the gratuity. That is a reduction in the employee’s rights, and it needs their consent like any other.
How to make a change properly
- Talk first, write second. Explain the change, the reason, and what it means for pay, gratuity and leave. An employee who learns about a change from a document will read it as an ambush.
- Put it in writing. A short contract addendum that names the clause being changed, the new term and the date it starts. Both of you sign.
- Give them time. Consent given under pressure on the same afternoon is weak consent. A few days to read and ask questions costs you little.
- Record it with MOHRE. Use the “Amend Work Permit and Contract” service on the MOHRE website or app, so the registered contract matches the real one.
- Update payroll on the same date. The contract, the work permit and the payslip should all say the same thing from the same day. When they don’t, the employee’s version usually wins.
If the employee says no
Then the contract stands as it is. You cannot impose the change, and you cannot punish the refusal. You can keep talking, offer something in return, or, if the role itself has changed, take advice on whether ending the contract is lawful and what it would cost. That is a conversation for a UAE employment lawyer, not a template.
What a good HR system does here
A contract change touches three records: the signed addendum, the MOHRE registration and the payroll. Most mistakes happen in the gaps between them, where a salary changes in payroll but not in the registered contract, or a basic salary moves and nobody re-runs the gratuity. An HR system should keep the three in step and show the gratuity effect of a change before anyone signs.
