Before posting anything online, ask yourself: ‘Could this get me in trouble at work?’
The first thing to consider is your privacy settings. These might depend on what you're using the account for. For example, you might use Facebook to catch up with family and friends, but you could be more open about who follows you on Twitter or Instagram.
If you’re using Facebook and want to keep it private, be careful about your settings. There are several levels of privacy to navigate. Even if your overall account is hidden, you might need to check individual posts to make sure they do not show up on a search.
You can also set custom audiences. This will be useful if you’re friends with people from work because you can decide what posts they see.
Take a look back through your timeline for anything controversial. And, if you’re using an account publicly, think every time you post.
