Any advice please. I started my role in February this year, the holiday year runs Jan-December. I work 25 hours a week over 4 days. When I use the gov.uk calculator to work out my holiday entitlement it gives me 31 hours for the year. 140 if I had started in January at the beginning of the holiday year. However, when I queried this with my employer they have come back that I am only entitled to 121? Is there a possibility that they have used another calculation that's available to them for it ? I am a permanent work and my hours and working days are set.
