I've added the audio series "English at Work" (from BBC Learning English) to the Business English > "Business Audio" section of ESL Links.
It's a story of people working in an SME (small or medium-sized enterprise) and they talk about a lot of typical business problems and use typical business English vocabulary.
It deals with topics like getting customers, disagreements between coworkers, pleasing the boss, business ethics, competing for promotion, holding meetings, making phone calls, and idioms often used in business.
Each episode is quite short (usually just a couple of minutes). And you can download the MP3 files (so that you can listen to them on your phone or media player) and PDF files with the script of the episode, so that you can also read what they say.
I've also linked to the version for China, which gives extra commentary, vocabulary & explanation in Chinese.
I feel it's a great way to get some practice listening to business English in a way that's interesting and funny (because it's series of stories with actors, not just someone reading business news). It also provides some insight into British business culture.
ESLpod.com has lots of free English Audio. (It also has learning guides, but you have to register and pay for those.)
Each has a short conversation, followed by an explanation of the words, idioms/expressions, ideas and culture referenceed in the conversation.
They are appropriate for intermediate & upper intermediate ESL learners.
Here are some of its podcasts related to ethics in the work place and in business.
