Do I have protection from day one if I am a part-time worker?

Yes. All 2026 day-one rights apply equally to part-time workers. This includes the removal of the Lower Earnings Limit for Statutory Sick Pay and the right to request flexible working. Your employer cannot treat you less favourably than a full-time employee regarding these statutory rights.

The Workers of England have a number of part-time members but receive full benefits of trade union membership.
