I worked for an organization on a salary basis monthly as a private contractor. There was no contract, and we had never talked about pro-rating salary.
I asked for payment in first week of September for work done in August, though it was a short month. The employer meanwhile was under the understanding that he was 'advancing' payment to me. This issue came up months later when I left the organization on the 1st of the month, and took the check issued on the 1st of that month thinking it was for the previous month's work. The bookkeeper claimed she didn't know I was leaving and made a mistake in paying me. The truth is, she didn't know the employer was paying me in 'advance' and had no reason to think they would do business that way. Additionally, they had paid me properly the year before - based on work done, not in 'advance'. I had no reason to anticipate anything else.
A year later they are still trying to collect that month's payment from me. They admit that it wasn't the smartest business practice, but it was a misunderstanding, and we should settle it amicably before they are forced to take further action.
Without a contract, without any offer to pro-rate the work I did do in August to settle upon a reasonable overpayment return - where do I stand?
Thank you for your help.
