Sounds more like an "entitlement" than a "requirement". Can't the railway company factor meal breaks into a shift?
Really, if anything, it sounds like office politics.
Not at all young man, the Offices, Shops & Railway Premises Act of 1963 was an Act of Parliament that EVERYONE on the Railway had to adhere to, irrespective of their position, or, work environment. ALL staff from locomotive drivers, guards, fitters, right across to cashiers, booking office clerks and Regional Managers, had to follow the law. Nowadays, even though quite a bit of the OSRP Act has been swallowed up into more modern Acts of Parliament, the health and safety aspect today still has to be followed to the letter, especially, even more so now that guards have added responsibilities and their job titles have changed to Train Managers, etc, since I was staff. So, it isn't an entitlement as you describe, but, a requirement of law. From memory we were allowed a 15 minute break between the 3rd & 5th working hour, so, if you worked an 8 hour shift your break from duty requirement was 30 minutes, which you could take at any time if you worked in an office, that was more flexible, but, for drivers and guards, it was rostered into their shift pattern and was taken when they could walk away from any rolling stock to a depot canteen, station platform staff room, etc, etc, I assume today's railway TOC's make provision for staff to engage in a proper break away from their ''mobile office'', at a time that suits them and Management, but, obviously not to the customer's liking, as per this Daily Mail article.
