I’m working 7-3 today. I had my 15 minutes at 10.45. Do I need to take a 30 minute before my shift finishes at 3 or can I just finish without?
It depends on the total amount of driving time in the shift.
For a shift that has between 6 and 9 hours working time you need a total of 30 minutes break/breaks, so assuming that your total driving time will not reach 4.5 hours you need another 15 minute break which cannot be at the immediate end of the shift.
If your total driving time is going to be over 4.5 hours and you did some driving before the 15 minute break then you will need another 30 minute break before exceeding 4.5 hours driving time.
