Fairly standard shoddy British construction practices for the age, and one of the main reasons we no longer have an industry worthy of speaking of.
Check out a documentary on YouTube, think it's called Clyde Shipbuilders. You'll know it when you see it, circa 1960-70 and it covers the workers as they try to strike (again) because their tea break which lasts for fifteen minutes, but which takes over 45minutes (time to get off ship and back on) is being binned by the new owners.
The workers attitudes are absolutely stinking. I won't spoil the outcome for you, but certainly worth a watch.
Biting the hand that feeds IT
