Hmm, how about things like tweeting links to your company's blog, your company's product, or your company's documentation? This probably happens a little bit less frequently but enough for us to at least take a cursory look.
While I would hope that most startups are above this kind of behavior, since startups tend to ask their people to use their personal accounts for marketing purposes, I have to at least have some concern...
Like I said downthread, reading the statute in the airless vacuum of a message board, it's easy to try to poke holes in it.
In reality, anything that amounts of an exception to the at-will doctrine creates an enormous minefield for employers. Terminated employees are very frequently disgruntled and can be counted on, over time, in the large, to bring meritless cases. Employers who want to survive without being stuck up for settlements are going to become very process-bound for how they handle credentials.
Think of it this way: worst-case downside to employee from this law: early termination. Downside to employer: horrifically expensive legal debacle.
