I use a computer and the Internet for work. I use a lot of software that is licensed to my employer.
Say some software licensed to my employer pops up its license on my employer's computer and demands that someone click an accept button. Or say that my employer has me, as part of my job duties, go to a web site that displays a terms of service and take an action there, like registering or posting to a company social media account. Or say that in the course of doing research that my employer has told me to do, I make a search on Google.com, which they would reasonably expect me to do but which I was not directly told to do.
How does the legal system determine whether the resulting contracts are with my employer as a corporate entity or with me as a natural person? How do I tell? Who is responsible for watching the terms of service for changes that my employer might need to decline, or knowing whether things that are warranted by the visitor in the terms are actually true?
