A job I worked at required that I acknowledge having received and read a pamphlet on sexual harassment in the workplace. My understanding is that it is a requirement of the state of CA that employers distribute such a pamphlet. The state even has a stock pamphlet that fulfills the requirement, though employers are free to substitute their own. My employer wanted me to acknowledge that I'd received the one via the HR website … except the link caused 500 Internal Server Errors.
I reported this, and even noted that if the link just goes to the standard pamphlet [and I linked to that] that we could consider the defect in the website "cured" and I could sign and life could move on. That part of the message got ignored, of course; the people responsible for the HR site are like "well it works for us?", and of course there's still pressure to sign a statement that I've read this thing.
All of that after I explicitly asked for any and all paperwork that would require my signature up front before becoming an employee. (This was, of course, not included in what I was given prior to starting.)
