When a corporation signs a contract, it's a contract with the corporation not with the CFO or whoever, i.e. it doesn't follow the CFO if they take a new job. Similarly, a press release is a statement by the company, not whichever PR person wrote it or the lawyer who approved it.

It's irellevent. The corporation doesn't decide to sign a contract, or to tell people to work from office or work from home, employees of the corporation decide to to that act.
