PostDoc advice - how to handle delay in training

Seeking input. I’m in a part-time clinical postdoc and in November was offered another additional position at another group practice. Seems like a good training opportunity and I respect the psychologists in the group. I bowed out of other opportunities when I got the role.

The problem is that I was offered the role in November with an early January start date, but I got a call from the owner of the practice the day before Christmas Eve saying that they didn’t know there was a timeline for getting me credentialed with insurance, and as a result I will have to wait 30-40 days before I can see any patients because they only just now started the process. Because I’m paid by the patient, this means my start date has been pushed back by 2 months at least. Keep in mind I did everything I could to get my provisional license in time by the start date, so did my part.

Now, an additional issue is that they know I’m going on maternity leave in April. The owner didn’t really apologize when telling me about this, just said that they were new to this and didn’t know and that I should just wait to hear from them. I asked if there was anything I could do - any cash pay clients, or training, etc. They said no.

I felt pretty frustrated that I was told this basically right before I was meant to start and that there was seemingly little attention paid to how this affects my training and hours - I’m a postdoc, not an employee after all.

So I’m now stuck, feeling frustrated, and wondering what if anything I can do. My partner suggested asking for a raise per patient to compensate for this very last minute loss in income. I’m curious what other people think. FWIW my contract has me as an IC (my choice) and the start date is listed on the document.
