ROG:
Why do so many say that 30 mins is required at the 6 hour point when there is no regulation that says that 
No idea ROG, I think they are just repeating what they have been told without checking or reading the actual regulations
ROG:
Is there something in the WTD regs that makes people think this 
Not as far as I can see, the section on breaks is very short and very clear so I’m not sure where they get it from.
Breaks
7. - (1) No mobile worker shall work for more than six hours without a break.
This bit lays down the maximum time you can work without a break, but makes no mention of how long that break must be
(2) Where a mobile worker’s working time exceeds six hours but does not exceed nine hours, the worker shall be entitled to a break lasting at least 30 minutes and interrupting that time.
This bit lays down the total amount of break required for a shift with between 6 and 9 hours of work, but does not stipulate when that must be taken, other than not right at the end of the shift, because you cannot interrupt something at the end.
(3) Where a mobile worker’s working time exceeds nine hours, the worker shall be entitled to a break lasting at least 45 minutes and interrupting that period.
This bit lays down the total amount of break for a shift with over 9 hours work but again does not stipulate when that must be taken, other than not right at the end of the shift
(4) Each break may be made up of separate periods of not less than 15 minutes each.
And this bit informs us that any period of more than 15 minutes qualifies as a break for the WTD
That’s it as far as breaks are concerned and nowhere in Section 7, or any other section, does it state a break of 30 minutes is required at, or before, 6 hours, and if it was required it would have to say as much.
Section 7 (1) doesn’t say how long the break must be and I can only assume they are then going to 7 (2) for the answer when in fact they should be looking at 7 (4). Section 7 (2) is about total break, not when during the shift it must be taken, only Section 7 (1) gives an actual time as to when a break must be taken. The worker may not know at the 6 hour point how many hours work will be in their shift so won’t know if Section 7 (2) or 7 (3) will apply.
Look at it this way.
7 (1) = When?
7 (2) = How Much in Total for 6 - 9 Hours Work?
7 (3) = How Much in Total for 9+ Hours Work?
7 (4) = How Long is a Break?
7 (1) + 7 (4) = Break Required at 6 Hours, not 7 (1) + 7 (2)/(3).
