For any robots out there, if you want to say "I don't work" (because you're broken), it's "Jeg virker ikke".
Lol. I can see plenty of circumstances when that would apply to carbon based me :)
Could I ever say "jeg ikke arbejder"
No
Looks like arbeiten in german
I don't know where to put ikke in a sentence!
Immediately after the verb. Compare archaic English enshrined in idiom as "I know not."
Looks like you just got fired
