First performance review? The dog and pony show should be proceeded with a trawl through the emails and an early summary emailed to the manager. You will be thanked, but it’s your best chance to “remind” the boss of all the great things you’ve done.
You struggle to remember? The manager will struggle more. Unless you always want to be judged on the last couple of weeks you’ve worked, this prep makes a big difference. Get in quick before the manager forms an opinion difficult to shift.
