I have had an interest in taxation throughout my adult life, and I recently stumbled upon a position at a Chambers to do exactly that, and they also pay for me to become a Barrister.
If I eventually get bored of taxation and I wish to go into Criminal, despite the extremely low salaries, what would be the process to make the change? It would be depressing to think I would have to go through some long bureaucratic process to make the change, unless it simply requires some work experience in the criminal side.
