Crappy external HR firms not understanding that freelancers don't just have an HR department you can phone up and grab a reference from. It's obvious from my CV what I've been doing for 14 years.
You've had my tax returns, invoices, bank statements matching invoices, personal references if you want to go and check them. I can't give you anything else. It's properly putting me on edge, I'm now talking myself into the job offer being withdrawn and it's messing with my bipolar, I'm getting no sleep, I can't eat properly.
Fuck you, Sterling.
