What are the standard holiday rules?
Under usual rules, workers are entitled to a minimum of 28 days holiday including bank holidays, each year. Except in limited circumstances, it cannot be carried between leave years meaning that workers lose their holiday if they do not take it.
The government passed emergency legislation relaxing the carry-over of the 20 days leave entitlement provided under EU law. Where it is not reasonably practicable for an employee to take leave in the relevant leave year as a result of the effects of the coronavirus then they could be entitled to carry over the untaken leave into the next year.
