Statutory Training- Ireland (and UK) employees

Hello all!

Noting the distinction between mandatory (required by the employer) and statutory (required by law) employee training, can I ask which trainings would be legally required upon onboarding for employees in Ireland?  The sector is Tech and many work in a hybrid/ remote setting.

I'm looking to answer the same question as well for UK employees which I will post in the UK discussion forum in case it doesn't pop up here.

Many thanks in advance,
