If I charge my iphone through a work PC USB, will all my phone data be visible?

Can my apps, emails and other iphone data be viewed by IT if the phone is charging on a PC usb

I highly doubt they will be able to view the contents of your iPhone, as well as the data you are sending/receiving. When you charge an iPhone, it is only providing power through the USB port. If however you actually sync the device to your computer, then they might be able to monitor it with some kind of software.
