How does your work do corrective actions? - Radgirl

I recently went from working for a national at home transcription company to working in a local hospital typing radiology reports.  The manager here has never worked at home and has no experiencing being a manager.  She has only ever typed in a dermatologist's office.  She is very strict about mistakes and putting them in our file.  If you have something in prelim that you are questioning and she finds an error somewhere else in the report you get docked for that.  If you have 3 mistakes in a year where they have to put an addendum, i.e. left instead of right, etc then you will get written up.  I try to do the best I can and we are all human and make mistakes, but this seems so aggressive.  There isn't a system for minor to major errors, they are the same across the board.  Put a comma in the wrong place, you're getting written up.  Plus, how about all the mistakes that I fix for the doctors and say nothing about.   I was wondering what other places do.  There has to be a better system that makes it less stressful.  I am constantly worried about everything I type.
