Workforce
Nothing big to really state about this. Not sure why Janeway couldn't have invited her fella aboard as a civilian though. I mean the real world aspect of new actor I totally get, but in-universe it could have been "You can come onboard, but you wouldn't be able to work because I'm the captain, but I realise that's not fair" "I got offered a promotion too" "oh in that case I totally understand, but hey, goodbye sex?"
Human Error
Chakotay/7 was one of those things I heard about that had always put me off watching on all of Voyager for a few years. Yet the introduction of it here is actually done half decently. Seven, finally has hit a point in her development where she actually wants to do more human things, but doesn't want to appear weak so does it in secret. Clever idea, and does fit the character quite well.
I'm sorta surprised the Doctor didn't mention that using the crew (or at the least Chakotay) in that way wasn't looked down well on, then again that she's actually exploring that side of her is a huge step forward, so he decides turn a blind eye.
I'm not sold on the relationship becoming a thing, but Seven side makes sense, from an almost teenage discovering her sexuality stand point anyway.
