Main concerns: attitude of management toward contractors, very low compensation
Clients may submit their dictations in any form whatsoever including noisy environments ie at a party, in a noisy restaurant, TV or radio blaring in background, chewing gum or eating while talking, several seconds (even minutes) of no speaking, flipping documents next to the microphone.
A typist may not reject a poor dictation for any reason whatsoever, even if you cannot hear it or understand due to poor equipment or noisy environment. Such dictations may be very long, thus tying up your ability to make money on a more professionally done dictation.
Contractors must make all changes that a client makes in a dictation, meaning taking out words already typed, and you are only paid for the final word count.
If you are a legal typist you are doing "legal" transcription and A LOT of medical transcription, as many of the clients are workers' compensation firms and the terminology includes very complex medical terms.
Especially for legal and medical transcription, the pay is very low - .5 to .55 cents per word depending on the day and time of day. Company lists compensation rate on their web site as up to .6 per word - but it is actually .5 to .55 per word. They also say you can make $15 an hour - that is very rare. (in several years I made that amount maybe 5 times)
flexible schedule and availability of work
Rude management, very low pay, poor quality dictations
