A Shepherd (FRCP) works in one trade through several posts at once, each kept to a solid standard. A Shepherd’s world, their work environment, stays the same, and each post shows the Shepherd a different part of that world, so a Shepherd sees one world from several of its places in the same week.
A post is any regular place in a Shepherd’s week, a hospital’s Saturday list as much as a club’s training night. Over the years a Shepherd takes up some posts, drops others, is promoted in one post and comes to serve new people.
A swimming teacher gives lessons at the city’s public pools for the council, coaches the youngest squad at a city swimming club and runs the summer courses at the open-air pool for a leisure company. The council, the club and the leisure company each pay for one post, and every post is swimming teaching. The swimming teacher sees the same children in the council lessons, the club squad and the summer courses, and can tell the club’s coaches which child is ready for the squad.
The pupils, patients or clients of each post meet the same standard from a Shepherd, whichever day of the week that post falls on. A new rule met at one employer, a better method seen at a second and a problem noticed at a third all reach the other posts through the Shepherd, often before anyone in those posts has heard of them. However, no single post shows all of this, so a colleague who meets a Shepherd in one post can take the Shepherd for a part-timer with one job.
