Translation of "gruelling" into Slovenian

This affects the working population’s ability to take on a heavy workload in a gruelling working environment.

To vpliva na sposobnost aktivnega prebivalstva za prevzem velike delovne obremenitve v napornem delovnem okolju.

We're all here to celebrate the end of this gruelling but short inquiry, thanks to her without whom it could never have happened,

Mi smo vsi tu, da bi proslavili konec mučne, a kratke preiskave, zahvala gre njej, brez katere se to ne bi nikoli zgodilo.
