Staff list: who gets unfair dismissal rights, and when

Paste your team from a spreadsheet. Each person gets a protection date, a status for today and the last day notice can be given so the effective date of termination falls before protection. The list stays on your computer.

How it works

For each person the tracker takes the start date, the contractual notice and the probation length. Protection starts on the day two years of service are complete if that is before Fri 1 Jan 2027; otherwise on the later of six months complete and Fri 1 Jan 2027. The six-month rule applies where the employee is dismissed before 1 January 2027 but the effective date of termination falls on or after that date, and does not apply where the effective date of termination falls before 1 January 2027.

The last notice day allows for the statutory minimum week that s.97(2) adds to the effective date of termination, so it is one week earlier than people expect when notice is paid in lieu, and the contractual notice earlier when it is worked. The one-employee checker shows the steps for a single person.

Frequently asked questions

Who is protected on 1 January 2027?
Every employee with at least six months' continuous service on that day: with the counting rule, anyone who started on or before 2 July 2026 (six months that begin with 2 July end with 1 January). Acas: someone will be protected if they already have at least 6 months' service on 1 January 2027.
What format should the staff list be in?
One person a line: name or initials, start date, contractual notice in weeks, probation length in months. Paste straight from Excel or Google Sheets; commas, semicolons and tabs all work, and dates can be 01/07/2026 or 2026-07-01.
Why is the last notice day earlier with pay in lieu than people think?
Because s.97(2) of the Employment Rights Act 1996 adds the statutory minimum notice (one week) to the effective date of termination for the qualifying period, even when you pay in lieu.
Does the tracker handle breaks in service or TUPE transfers?
No. It assumes continuous employment from the start date you type. Breaks, re-hires, TUPE transfers and earlier service with an associated employer can change the date: check them with Acas or a solicitor.
