So what if the company pays for the adr course but are doing it off your own bat? Either way id zip it
Answering the OP’s very straightforward question… There’s only one issue.
The thing that makes the difference is who made the decision to send the driver on the course, which is either the driver OR the boss.
Whoever is paying for the ADR course makes no difference as to whether the time spent on the course is recordable as working time.
There are a few reasons why a driver who pays for their own course in their own time might not wish to tell the boss that they’d been on a course.
