That really depends on what you mean by "any system." An employer can certainly record telephone conversations that use their phones, computer communications that use their systems and things which take place in public areas within the workplace (like break rooms, hallways, etc.).
For recording on their systems, they don't require your permission and don't have to give notice (though they would for recording conversations with the public for training purposes). For workplace locations, they just have to provide notice that it can take place...they don't need permission. You then have the choice of working under the conditions or quitting.
As for any other type of recording, you'll have to be more specific for me to address that individually.
If you have any further questions, please let me know. I invite follow up questions, so use REPLY for those.
