There should be a training checklist of the skills / tasks you need for the job, with training / certification either obtained OJT, or prior to you being allowed to perform certain tasks or operate certain equipment (likely a combination of pre-certification and OJT).
And, there should be an agreed-to-plan and schedule as to how you obtain that training and certification. e.g., what days / shifts? will training be done on non-work shifts, or squeezed into your working shifts?, will training be group sessions or 1-on-1? who is training you on each task? what are the standards / tests required to demonstrate competency.
Any organization which lacks that level of detail doesn't have a true training plan.
Any organization which doesn't see training as a 50/50 responsibility between employee and trainer doesn't have a true training plan.
Any organization which lacks a recurring or ad-hoc recertification test or audit isn't serious about maintaining safety / skills.
But, more importantly, congratulations on the baby. They don't come with training plans or checklists either. But, that's OK
