I also understood, that from now on the person works on weekend. Maybe somebody could explain, why it doesn't work?
I thought ik verbs took the om ending in the first person singular? Why is it ok here and why is dolgozom marked wrong?
-ik verbs are nasty, even for native speakers. To me, both "dolgozok" and "dolgozom" sound natural.
IMHO that not "this weekend" (ez a hétvége) but generally "on weekends" (hétvégén)
