Increased control by the executive branch of any and all external communication by employees
This has been an issue for some time. In DC, under the Fenty Administration, many of the agencies lost their public information officers, and communications came out of the mayor's office. This has continued under Mayor Gray, when the director of the Department of the Environment and the Insurance Commissioner were fired because of external communications that the administration didn't like.
I learned this in my brief experience working for government in Baltimore County, when my press releases and certain external communications were handled by the County Executive's press people.
But it's a problem "everywhere," especially because officials don't like counter-information, criticism, etc. WBEZ Radio in Chicago just ran a story, "Chicago principals say they operate under 'gag order'," about how principals of Chicago schools have a gag order imposed by the Emanuel Administration and some have been reprimanded for speaking out.
This is one of the downsides of Mayoral control of school agencies. But it's a problem in any case.
"At-will" employees are always at risk of losing their jobs when they don't toe the line. That's why I argued in this past blog entry, "DC Government at-will employees need protections to tell the truth," that local government deserve protections so that they can tell the truth without losing their jobs.
