Just a note of corporate business communications policy, any business. Before my company puts out something to the pubic, it passes multiple levels of review to include Senior Legal VP, Senior Communication VP etc, etc.
There is NO way a major and reputable law firm would allow anyone, associate, partner etc, publish anything on their official page with their letter head without it being reviewed by senior partners and the compliance team.
The fact the author who is an associate, as opposed to a partner, does not mean anything as to his bona fides as far as the law goes. Also, unlike you, he is an actual attorney in the venue in question ref the MLBPA CBA.
So, in other words, your point is 110% moot.
