Like anything it’s a challenge but a worth while one.
If your successful in getting a place then they will train you up, give you a new skill set, take you under their wing and develop your skills base and you as a person. They pay you food and travel expenses so you are not out of pocket and all they ask is to guarantee you’ll give them the equivalent of 4 hours of your time a week. If like me you’ll thrive and want to put in more than 4 hours. As they they say, you get out of something what you put in.
If your concerned about impacts on family life then think about what an impact studying would be, financially and time wise. In fact think how much time and money you put into cycling or any other hobby. If you are interested in a job in the regs then its a no brainer.
Once your through the training you pick and choose what hours you want to do and when. Nothing is forced on you. Your a volunteer and its in there interests to keep you sweet. I tend to do at least one shift a week but it barely affects the family. On a Thursday night, for instance, I might hit the station after work and do 18:00 – 00:00. I’ve done 150% of my requirement in one evening and lost no more family time than if I’d gone riding.
