Surely if a company wants their handlers and dogs to maintain a level of training and the handlers are 'employed', as opposed to self-employed, then that cost should be bourne by the company. Most handler wages are appalling as it is, without deducting more.
The majority of handlers I know train during their own time and therefore don't get paid for it. They do it in order to improve their effectiveness and ability.
I understand the need for a company to pay a trainer in order to conduct training days etc, but can't see why this cost should be passed to 'employees'. As a self employed handler, I would expect to cover my own costs.
Are we talking about employed handlers here, or am I woofing up the wrong lamp post!?
