Employer businesses in the UK affected by these changes

Day 1

SSP and paternity leave rights now apply from the first day of employment

2025-28

Phased rollout — new obligations arriving every 6 months through 2028

Small businesses (1-49 employees): You're most at risk. You probably don't have an HR department. Your employment contracts likely need updating. Your SSP calculations have changed. Your dismissal procedures need reviewing.

Medium businesses (50-249 employees): You need to audit your zero-hours contracts, update your sick pay policies, and consider menopause action plans (mandatory only for 250+ employees from spring 2027, but best practice for all).

Larger employers: Trade union access rules are changing. Fire and rehire restrictions are tightening. Tribunal time limits are doubling.
