I emailed my boss last night and let him know I am most likely going back to my old employer as they have offered me substantially more money, the hours are better, and commute isn’t as long as it is with my current job. He emailed me this response. I went on to have a 20 minute conversation with him on the phone in which he said he would need 6-8 weeks to fill my current position. The company states 2 weeks is the minimum notice in order to be considered for rehire (want to keep my options open in the future as this company is expanding).
Any advice on how to navigate this? I have an interview with my old employer tomorrow in which I will accept the job (the interview is a formality). My current boss wanted to touch base tomorrow after the interview to discuss next steps. He is very overbearing and I am not sure the best way to handle pushback.
