As much as one would wish and hope that institutions such as the SPCA would screen for applicants who love animals during their hiring process, or give priority to the ones that have a degree, or diploma of some kind, related to animal matters; it is equally if not more important that these same people receive the best education, training and apprenticeship after they are hired. Dealing - day in, day out - with various kinds of animals in all kinds of circumstances requires highly skilled people. A select minority comes with these skills, may it be God given or attained by past education, training and/or experience. The onus lies with the organization to educate and train the rest, and get rid of those that do not make the cut. Handling animals is no different than handling industrial machinery. It must require credentials regarding maintenance, skilful operation, and troubleshooting. Otherwise - same as with industrial machinery - one will damage the equipment, destroy the project, or seriously hurt oneself, the public, or the team. Without impeccable credentials one would never be allowed to go near industrial or sensitive equipment. Why should it be it different with animals?
