I somehow do not think OP is working for themselves. They are a contractor there. I do believe contracting is just being an employee on slightly different terms.
> I work alone and only have one reputation. I don't want to be that contractor forever known for destroying a clients business.
Hard to say, interesting observation:
> I am currently supporting four wineries that are processing thousands of tonnes of receivals 24x7... I don't want to be that contractor forever known for destroying a clients business.
If the 'clients' being referred to are the wineries, then it sounds like a self-run company. IE: the company is operating as a contractor to the winery clients, for whom (the wineries) a failure of the contractor (the company) would be a disaster for their business (the client, the wineries).
OTOH if "clients" refers to the business (the company) that in turns does the support for the wineries, then yes - an individual contractor.
The distinction would seem to me to really change the entire tenor of the comment. I'm curious which it is.
