New starters in any organisation are at their most impressionable during their first few days and weeks.
They are keen to find out about the culture – about the predominant and recurring patterns – so they can use these as guidance to help them operate successfully in their new job.
Examine your onboarding process and notice what messages and signals it sends to the new starter about learning transfer.
Are you mostly exposing them to content without any activities to enable them to use that content effectively on the job?
Are you pumping and dumping content before they have even seen the context where it applies?
Are you cranking the handle so you can tick the checklist and get them through and into the trenches quickly?
What is their line manager telling them about the induction training?
My best wishes, Paul
