Read his example again, it looks correct to me.

worked 21 calendar days in a row
It’s not legal to work 21 calendar days in a row. No ifs, no buts.
Hi Harry you are right you can’t work 21 calendar days in a row.
If you look at the example a day for that driver is a night shift and on Sunday night in each week no work was done, so in fact the op example was 6 shifts in a row, and because the shifts cross the day/night line it would appear to be working 21 calendar days.
its an elusion of consecutive working, but a rest as been done in each week as required, and one of them was to cover the 6x24 hour periods or 144 hours, but was not needed for the op scenario, but the next one would be an official rest and could be a reduced rest( any hours less than 45 hours is a reduced rest).

@ROG, what about
‘in two consecutive weeks there must at least one Weekly Rest Period’ ?
If your example the first week has a full Weekly Rest (because of a holiday) then a Reduced Weekly rest.
The following Weekly Rest cannot be reduced because it is consecutive to the reduced rest that went before.
Otherwise, we would all be trapsing about doing twenty one day weeks already.

Look again …
Week 1 has a full
week 2 has a reduced
week 3 has a full
Where has the law been broken?
The emphasis in the rule is in ‘any’ two consecutive weeks there must be a Full Weekly Rest and one Reduced or two Full Weekly Rest periods.
The phrase (which is in a prominent position at the end of Weekly Rest paragraph in the VOSA Guidebook)…
… means although the period of work in your original example is bracketed by Full Weekly Rests they are irrelevant because the two Reduced Weekly Rests that give us twenty one working days are consecutive.

I give up, I’ll just wait for Tachograph or Coffeeholic to arrive.
Who will say the same as Mike and I 
I’ll say the same too it is perfectly legal and i’m pretty clued up on the regs. Delboy explained it well.
