Context: Worked at a boutique consulting firm this summer and loved it, especially my team and my manager who was very empathetic and caring. Received a PPO.
Problem: Given family financial circumstances (primarily) I had to think beyond my interests and hence sat for placements and received a placement from a much bigger consulting company. I now feel super guilty and do not know what to do. I eventually want to come back to the boutique firm as it specialises in a niche I care about (once family issues sorted).
Question: Is it wise to be fully upfront, first tell my side of the story to my manager asap and reject PPO politely? If not, what is a good way to do it?
TL:DR - How to reject a PPO after accepting it?
Any honest opinion and advice would be highly appreciated. I understand I have put myself in this complicated situation.
