In the comments on a recent post about blogging with your name attached to it, Andrew asks:
How would you feel, as a manager, if one of your employees kept a blog? I feel like you may be on the progressive side of the spectrum, so I'll follow up with: how do you think MOST managers feel about this issue? Is it an issue people should legitimately be worried about?
I think it totally depends -- mainly on what your blog is like, but also on your company and your manager.
For instance, I once learned that an employee was writing a blog that contained fairly extreme political positions. He was working on a state political campaign for us at the time. The blog had to go -- had it been discovered, it would have reflected on our campaign, despite the fact that he was doing it as a private individual, not as a campaign staffer.
That's an extreme example, but it makes the point: If there's any chance that your blog would reflect negatively on your employer if people knew you worked for them, any smart employer will have concerns.
Now, what kinds of things might raise concerns for them? In some environments, politics will. In almost all environments, sexually explicit content will. Glorification of drug and alcohol abuse. Complaining about your company, your boss, or your co-workers. Also, things that just make you look bad -- incoherent ramblings, for instance.
On the other hand, it's possible that your blog might reflect well on your employer and actually be seen as a bonus. For instance, I write my blog on my own, not as a representative of where I work, but it's nice for my employer to be able to say, "Alison writes a pretty well-received blog about management issues."
(Of course, if I were giving out horrid advice, that would be a different issue.)
Personally, I think the litmus test should be this: If your blog were for some reason featured in a company newsletter that got sent to all clients and staff, what would happen? If the answer is "boredom" or "acclaim," you're on the safer side. If the answer is "raised eyebrows," "offense," or "shame," you're in trouble.
But it's true that there are some managers who would be worried about anything that isn't, say, a cooking blog. If you work for one of those, stay anonymous.
