Detail work - managing the inflows and outflows of money in an organization. It requires basic math skills, attention to detail, and computer skills. Is McDonalds a financially healthy company?

Word Processing Specialist
This is basically typing for a living. You'll input data into computers, be dictated documents to be typed, etc. Anyone can do this.
Marketing Management
