I have accepted a permanent manager role with a very good salary at company A and resigned from a team lead role at company B. I am supposed to start at company A on Sep 14.
However, my personal circumstances changed in the meanwhile and am in need of more money. I therefore applied for contractor roles (non-manager) which pay significantly more. Now I have been offered a contract role with company C.
Can I give notice or resign to the job at company A one day before starting?
