hi easy chic, adam's right its a good side line to have and varies, depending on when they need you but generally you do about 5-10 days a month. the trips away are normally just for 2 or 3 days and are very rare as they try to spread them out a bit. You get looked after well, and fell like you're really making a difference (especially when you recruit someone for you own base!). The office day pay is very good, if you think you'ld like it apply otherwise there will be loads of peole after the posistion, there were last time. Before this year the recruitment team haven't been after anyone for the team for years, and some people have said that they waited years to apply! so it's up to you, but dont waste time thinking about it as the posistion will be filled extremely quickly, and then you may miss out!
