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 prepare for menopause action plan requirements.

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