Ideally part timers would work whole days rather than part. Half days are OK, but typically better in the mornings when 65-75% demand arrives. A handy tip to organise the session is: start with lots of online and telephone responses. If you decide to bring in, put the first one at the end of the session. Work forwards with F2Fs, until you are bringing down now. Stop the callbacks, have a coffee and spend the rest of the session seeing F2Fs.
Our training partners are able to advise on how to structure the day for your practice needs.
