From the Article -
"Most employees believe that employers should invest in their future by providing skills training, and younger employees have higher expectations, according to the report. In Germany, 69 per cent of employees aged 18 to 29 agreed with this, while in the UK, the age category agreeing most was those aged 30 to 49, at 65 per cent."
You might well find the difference in the age band between the UK and Germany is down to the training available to the differing age groups.
In the UK, it's not uncommon for companies to invest in early years training, which then tapers off significantly by the time you reach 30.
I don't know the situation in Germany, but its possible that the reverse is the case there.
