I used to undertake work for a company on a retainer basis, which was fine as it was my DH's company. Things have changed and it is no longer his company, but they still wish me to undertake work for them.
They wish to change the working structure to quote for separate pieces of work, which I said I was happy to do. However this will be difficult for many things such as updates to documents, website etc, where updates will come at different times and may include minor or major changes.
They have stated in a letter that they will not pay for anything which has not been agreed down to the last penny. They will not accept anything other than fixed fees and much of the work cannot be done in this way without me losing out.
They now seem to treat me as an employee, dictating when I will be available for work (even though my other clients pay more and are flexible) and expect me to constantly be in contact about the work. The way in which they speak is very patronising and condescending and I have had enough.
I feel that as DH still works there they feel that they can treat me differently and expect much more than the usual working relationship that I am used to.
How can I politely say that I am not their employee and I will complete their work by the deadline and provide updates at mutually convenient times? Or should I just tell them to stick their work and hope that DH does not suffer?
