The answer is: Yes and no! Because it depends on whether your staff are salaried or they get paid hourly.
Those that you pay based on the number of hours they work should get paid for working an extra day.
Meanwhile, salaried staff should not ordinarily get any extra pay.
But if salaried staff are paid only National Minimum Wage, or very close to that level, then there’s a risk that the leap day might accidentally mean that their earnings are below the legal minimum.
Our advice is to check the wording of your contracts now and establish if there will be any breach of National Minimum Wage.
