This month's question:

Is there a statutory maximum as to the number of hours an employee can work? 

Under the Working Time Regulations (Northern Ireland) 2016, adult workers should work no more than an average of 48 hours per week (averaged over a period of 17 weeks), including overtime. Employees can opt out of the maximum weekly working time limit.

The following activities in addition to the employee’s normal duties are counted towards the number of hours worked in one-week: job-related training, working lunches, time spent ‘on-call’ at the workplace, time spent working abroad, travelling to a customer or client, for example if the job is a travelling salesperson. However, the working week does not include rest breaks when no work is done, such as lunch breaks, routine travel to and from home and the workplace (if the person has a set workplace).
