it will be hard for most people to leave voluntarily in the 4th quarter. the job market is typically tight at year end as many companies lock down their budgets.
good news is that most companies start the year with a fresh budget and job openings so dust off those resumes and get ready for 2021. first quarter is a win win for employees. if you can milk it until year end, you qualify for sti, if any gets paid this year. then you can productively job search in january/february. this is why you see the mass exodus every year when sti is paid in march. if done properly, you get the absolute most from aig before you finally find sanity at a good company.
bottom line, leave now if you can, leave later if you have to, but leave. 2021 will not be a pleasant year at aig unless you are in the executive circle.
