The limits
What a limit is made of, which ones apply, and the part of each that is usually got wrong.
What a Limit Is Made Of
Every working time limit has four parts, and most arguments about overtime compliance are arguments about one of them that nobody has named.
Which Limits Apply Here
Most organisations are under more limits than they have written down, and the ones they have missed are attached to a group of people nobody thought about.
What Counts Towards a Limit
Organisations usually get the number right and the thing being counted wrong, because the number is in the rule and the definition is two paragraphs earlier.
Caps, Triggers and Thresholds
Three different kinds of number get called a limit, and treating one as another produces either an unnecessary refusal or an avoidable breach.
Night Work Has Its Own Arithmetic
Being a night worker is a status acquired by pattern rather than by job title, and most people who have acquired it do not know, and neither does the rota.
Workers Under Eighteen
Stricter limits apply to young workers, few rota tools implement them, and the people scheduled past them are the least likely to object.
Where a Sector Regime Takes Over
Some kinds of work are governed by their own hours rules, which usually replace rather than supplement the general ones, and the boundary is where the mistakes live.
