A NASA employee based at the Johnson Space Center is currently serving a 180-day suspension without pay from their position because they wrote politically partisan blog posts, solicited donations, and sent emails while at work.
In all likelihood, the employee would have been suspended whatever method of communication they’d used to air their political views, and whether or not they’d done so at work or in their own time, thanks to the Hatch Act, but the fact remains that another blogger has found themselves in hot water.
Perhaps said employee would have done well to heed this advice — Big Brother is always watching. If you’re doing something which contravenes your contract of employment, expect to be found out. Blogging is no exception.
