Sou is a Monday to friday base, working either earlies 6am till 1300 (just 2 sectors then a standby), or lates 14:00 till around 21:00 (4 sectors). There is one J41 based there, with another aircraft kept for charter work.
In practice you may spend time at other bases and away on charters from time to time, including weekends.
The terms and conditions are fairly basic, but the crews are generally decent to work with.
