If something is public record, like an outage schedule, it is not a violation, free press applies. If it some trade secret, that is not allowed. It is unwise to list an exact salary as it could vary, but if you gave a range like Sr. Hp's get between 20 to 25 dollars and hour depending on experience if you know it is true and you label it as your opinion, not guaranteed, again, you are entitled to give an opinion. For example, if it was my opinion that Catawba pays $19 to $24 dollars for a senior, and I feel it is the lowest in the industry, I am entitled to say so. Now if you say "Catawba treats their workers like trash" be ready to back it up or you libel them. Do let the companies intimidate you from legitimate free speech.
