maximum hours allowed to work before a break
If you are aged 17 and 18, you can work up to a maximum of 8 hours per day and 40 hours per week. You must have a break after 4.5 hours of work and a break of 12 consecutive hours after an 8 hour day.his does not mean that it is prohibited to work more than these hours in any week, nor does it mean that one can stop work when you have worked 48 hours in a week. However it means that on average your working time should not be greater than 48 hours. An exception is night time working where the maximum is 8 hours.
