If her web browsing starts affecting her job and completing tasks in the requested time, well that is a whole different story.
That's just it. She takes 8 hours to do 4 hours of work. The other employees are pissed because they have to do more. It's a real mess. I should have, uh, stated this at the beginning. Her fortunes are starting to look more bleak as I type this, I think.
If the above is true then I would be looking for another employee.
