I don’t know of one case where social pressure caused a husband to give a Get. The only thing that is accomplished is that the husband has been embarrassed. It should be noted that the second Bais HaMekdash was destroyed because Bar Kamtza was embarrassed even though he was an evil man. It should also be noted that one who embarrasses his fellow Jew loses his portion in the next world.
Informing an employer may get you sued for defamation of character. I know of a Bais Din that has been sued for issuing a Siruv. You do realize that the husband can go back to civil court and ask that his alimony and child support be reduced as the wife’s agents are trying to get him fired.
