Over a week ago I gave my notice verbally. It was clear it would be accepted from that date. At the same time I discussed reducing 12 week long notice period and was told I'd get an answer in two days. Obviously new job would prefer me to start sooner and I told new job I'd know on X date.
Old job proceeded to start telling people about my resignation (without confirming to me they would/had) but I have heard nothing from my manager or the rest of the senior team since that first conversation. Except for one message 2 days later asking me to follow up with written notice. I replied and again asked about last day - no reply, not even to say they'll discuss it on X date and let me know. I followed up and provided written notice.
Heard nothing this week either and I'll have to go back to new job again tomorrow and apologise for the delay again. I can't sign my new contract as they can't put the right start date on and I'm a bit worried the delay looks like its coming from me and it might cause them to rethink.
AIBU to find this a bit annoying. And if I am how should I be approaching it instead?
