I've been with my current company (Company A) for about a year and 4 months. A couple of months back I decided to start applying for new opportunities due to issues with my pay and personal growth.
A couple of weeks back I received a great offer from Company B, and I put in my 4 weeks notice of resignation with my Company A. Unfortunately, due to concerns about COVID-19 and the global economy, my offer from Company B was rescinded just recently. I swallowed my pride and explained the situation to my Company A and asked if I could remain. They agreed, which I am very grateful for, and have proven themselves to be very supportive.
However, the issues with pay and personal growth are not going to go away. I still want to leave Company A. I'm still going through the interview process with some other companies that I think could be great opportunities, but I am acutely aware that if I received another offer from say Company C, and that is also rescinded, its highly unlikely that my Company A will take me back a second time.
That said, I think it's also unrealistic to expect/force myself to stay with my Company A for much longer just because they helped me out, especially when I know that the issues I'm concerned about aren't going to go away.
This seems to be a very fine balance and I have no experience dealing with this situation. I've never had a job offer rescinded before.
Is it acceptable to remain with Company A and immediately continue looking for new roles, and possibly "resign" again within 1 - 2 months? If not, what is the acceptable amount of time before I resume my job search?
