AP union says no tweeting

In dicey union negotiations, it seems the modern silent protest is an embargo on tweeting.

Representatives for the News Media Guild are urging union employees of the Associated Press not to promote their stories on Facebook or Twitter early next week.

Reporters often volunteer to spread links out of good will for their employer or for obvious narcissistic reasons. The labor union is discouraging people whose job explicitly entails using social-networking services from participating in the boycott.
