I've worked for a great owner in the past, but the owner/operator I now work for is childish and emotional/unfair in their approach to management and operations. It all comes down to the bottom line, as corporate as it comes. That's why I became a therapist was to move out of corporate world and be treated like a person and not a money maker (asset/deficit).
The wrong operator approach and you will be used up and burnt out. I'm 51 years old and in really great health, but I know my limits as a therapist. Problem being, you ARE NOT IN CONTROL of your existence and you will be taken for granted and advantage of in a heart beat. You will be ignored when you demand a break in the middle of your shift in lieu of selling a guest at that hour for your 4th straight hour of service. You will be ignored when you state that you don't do deep pressure work, AT ALL. You will be treated like a slave, piece of property, insignificant and replaceable. You will be written up if you decline to work on a client for these reasons.
