The Supreme Court has now confirmed that all part-year permanent workers – namely those who are employed throughout the year but don’t work every week such as those on zero hours, ad-hoc or term-time contracts – are entitled to 5.6 weeks’ paid annual leave in each leave year, and this leave cannot be pro-rated according to the number of hours worked.

As a result, many employers will need to rethink how they calculate holiday entitlement and pay going forward and decide how to deal with any past underpayments as a matter of urgency to avoid the risk of holiday pay claims.
