Do corporate conflict of interest policies implicate blogging?

I imagine if posting is excessive (even during non-work hours):

No employee shall undertake any outside business or volunteer activity which might be so time and energy consuming as to impair his or her effectiveness with [company], without the approval of their manager. This applies not only to outside business but to charitable, recreational, educational and civic activities as well.

I'm surprised this list didn't include familial.

Part II
It seems to me that if the company employs non-degreed persons for similarly situated tasks, then the employee should be able to engage in the practice of law without express permission.

Should an employee be required to hold a license to practice law as a condition of their job, it shall be unacceptable for such employee to practice law other than in the course of his or her employment with [company], without the express permission of the employee's manager.
