if the cause of burnout is from overwork, then instead of moving, i'd consider part-time (say, 3-4 day work week).

If the cause of burnout is disillusionment - aka, you are such a small cog and your work doesn't seem to matter, despite how hard you actually worked - then moving to a different, but still big company, will not change that. Startups, imho, is where to move to, in order to feel impacts.

If the cause of burnout is project-based - aka, you just don't enjoy or feel the project is worthwhile - switching companies might work (a different project).

There's many other causes of burnout, and each will require individual solutions - there's no one size fits all.

From experience, 4 day week doesn’t really help. You end up doing just as much work as people on 5 days but getting paid less, getting overlooked because you’re less present, and consequently feeling resentful AND overworked. A 4 day week is great for other reasons though.

either you're doing too much work, or everybody else is doing too little. Cut back.

As for promotions, if you intend to do 4 days, prepare to face zero career progression in the same company - unless you're extraordinary and indispensable. But this is the price you pay for a 4 day at this point.
