Some research help please.

I am interested to know what topics or areas you as a company find yourself doing training on or sending for. perhaps also would like to if time and money allowed.
I am particularly interested on what would be ongoing, almost year in and year out, at what ever level and quantity.
As an example product knowledge to new sales people would be an ongoing thing. perhaps IR for supervisors and such forth

I exclude for these purposes, company specific stuff.

look forward to the replies
