As I said, this is important both for the worker themselves; we want to make sure that they don't have to come into work when they're unwell, because of a lack of adequate sick leave. It is important for the co-workers, for everyone else in the workplace. We've learnt through the course of COVID-19 that bugs do spread, and, of course, if someone comes into work when they are sick, those bugs spread to other people and potentially have a bigger impact on that workplace than had the person taken a couple of days to get over it. A study in the United States in 2015 revealed that workers coming into a workplace when they were sick decreased productivity in that workplace by 20 percent in the period concerned.
