They are entitled to at least one day (24 hours) off each week, although this can be deferred (but not abandoned) in particular circumstances: for instance, where there is a high level of seasonal work, or where round-the-clock working is required. The 24-hour break each week can currently (if it suits you as employer) be replaced by two 24-hour breaks, or one 48-hour break (24 hours back-to-back) in each 14-day period (but see question 13).
