Resignation letter Ireland: how much notice you actually have to give

The minimum notice you must give your employer in Ireland is one week, and only once you have thirteen weeks' continuous service. That is section 6 of the Minimum Notice and Terms of Employment Act 1973. It is a flat week. Unlike the employer's ladder, it does not increase with service. A longer period in your contract is enforceable as a contract term, but it is not the statute.

The asymmetry most templates get backwards

Section 4(2) sets a ladder that binds the employer: one week under two years' service, two weeks to five years, four weeks to ten, six weeks to fifteen, and eight weeks at fifteen or more. Section 4(1) starts that duty at thirteen weeks' service.

Section 6 is what binds you, and it is one week, full stop.

Section 4(5) — the subsection that reads a too-short notice period up to the statutory minimum — is written against subsection (2). It protects the employee. It does nothing to shorten a three-month contractual period you agreed to give.

Under thirteen weeks, you owe nothing

Section 6 applies only to an employee who has been in continuous employment for thirteen weeks or more. Below that, no statutory notice is owed at all — and none is owed to you either. Your contract may still say something, and it is still a contract.

Leaving without notice, and the three lawful routes

There are exactly three:

1. The employer waives it. Section 7(1) provides that nothing in the Act prevents an employee or an employer from waiving the right to notice on any occasion. Get it in writing.
2. Payment in lieu is accepted. Same subsection. Section 7(2) then treats the termination date, for the purposes of the Redundancy Payments Act 1967, as the date the notice would have expired.
3. The other party's misconduct. Section 8 preserves the right of either an employer or an employee to terminate a contract of employment without notice because of the misconduct of the other.

What your employer can and cannot do if you leave early

Leaving before your contractual notice runs is a breach of contract. The employer's remedy is damages for the loss actually caused — the cost of cover, usually — and it is rarely worth pursuing. A court will not order you to work.

What the employer generally cannot do is take it out of your final payslip. A deduction in respect of an act or omission of the employee has to satisfy every condition in section 5(2) of the Payment of Wages Act 1991:

• it must be authorised by a term of the contract of employment (section 5(2)(i));
• it must be of an amount that is fair and reasonable having regard to all the circumstances, including the amount of your wages (5(2)(ii));
• you must have been given a copy of that term, or written notice of its existence and effect, before the act or omission (5(2)(iii));
• you must be furnished with particulars in writing of the act or omission and of the amount at least one week before the deduction is made (5(2)(iv));
• the deduction must not exceed the employer's loss (5(2)(v));
• and the first deduction must be made within six months of the act or omission becoming known to the employer (5(2)(vii)).

Section 5(4) makes the term itself unenforceable if the deduction does not comply. An unlawful deduction is a WRC complaint with a six-month time limit.

What must be in your final payment

Section 23(1) of the Organisation of Working Time Act 1997 requires the employer to pay you, as compensation for the loss of it, an amount equal to the pay you would have received for annual leave accrued and untaken in the relevant period, at your normal weekly rate or a rate proportionate to it. It cannot be forfeited by a "use it or lose it" policy.

Section 23(2) is the one people forget. Where your employment ends during the week ending on the day before a public holiday, and you have worked for the employer in the four weeks preceding that week, you are entitled to an additional day's pay for that holiday. There are ten public holidays: the nine in the Second Schedule and the first Monday in February, prescribed by regulation 4 of S.I. No. 50 of 2022 — except in a year in which 1 February falls on a Friday, when regulation 5 moves the holiday to 1 February itself.

What to put in the letter

Keep it short and put four things in it: that you are resigning, the position, your last working day, and — if you are giving less than your contract requires — which of the section 7 or section 8 routes you are relying on. Ask for confirmation of the last day and for the final payment to include accrued leave. Ask for a reference in the same letter; it is the easiest moment to get one.

You do not have to give a reason. The single case where the reason matters is where you are leaving because of how you have been treated — then the letter should say so, because section 1(b) of the Unfair Dismissals Act 1977 defines a dismissal to include a termination by the employee in circumstances in which, because of the conduct of the employer, it was reasonable for the employee to terminate without notice.

Send it so you can prove you sent it

Email it to your manager and to HR and keep the sent copy, or hand it over and ask for it to be signed as received. The date the resignation was given fixes when the notice period ran and when the six-month WRC clock started.

Our resignation letter sets the notice correctly against your service, lists the leave and public-holiday pay you are owed, and blocks a notice period section 6 does not permit without a recorded waiver.
