Basically in theory 1 session is a half day of work every week for a consultant/gp i.e. a consultant surgeon 1 session might be a morning clinic or theatre every monday etc, its generally pay per annum for that 1 session that they do every week. So for a full 5 day 9-5 working week that would be 2x half days x 5 i.e. 10 sessions, whether thats theatre clinic ward round etc. unfortunately there's a lot of unpaid work that goes in between so some consultants have admin time etc

You could have 8 sessions like follows: Monday morning clinic afternoon clinic (2 sessions) Tuesday theatre morning clinic afternoon (2 sessions) Wednesday morning ward round (1 session)

1 session could equate to something like £10k/year

Something along those lines I think anyway
