Chances are most office employees have raised their voice on the phone at one time or other, but don't make a habit of it. "You have to respect that other people can hear what's going on in your cubicle. That means don't use the speakerphone to dial numbers or hold conference calls in your cubicle," says Robert Hellmann, a career consultant with The Five O'Clock Club, an outplacement firm. Likewise, he urges employees to avoid talking too loudly while having overly personal conversations in the workplace, as this can be "painful" for others to overhear. Instead, Hellmann suggests finding an open office or conference room you can step into to take the call, and if you really need to have a shouting match with your spouse, it may just pay to go outside. Listening to loud music or videos
Along the same lines, listening to loud music or videos at your desk infringes on the personal space of others around you and could create a tense work environment. "Every company has a different policy about earbuds, but if you are listening to music, either close your door or put on earbuds," Glickman says. "No one wants to listen to Guns 'N Roses just because you do."
