The general advice to get it in writing applies equally to everyone whether they are freelance or self–employed, workers, casuals or employees.
If you do not have a written contract you should try and confirm in an email or letter what has been agreed on the telephone, setting out dates, hours of work and rates and make it clear this is what you expect the arrangement to be.
In every case, freelance or employee, you should ask them to come back to you if they disagree with your letter or email.
