I'm about to start in a new more senior role at my current workplace but have already had a few dealings with who will be my new manager. She doesn't respond to emails ( I emailed asking for something to be reviewed a few weeks ago. Emailed again after 1 week, printed it off and left it in her desk with a note a week later and have chased in person again today ), how do you manage this if your in this situation? She invited me to a meeting a couple of hours before it was due to start and ever since treats it like it's my project deferring to me in meeting with externals. I haven't even actually started the job or signed a contract yet.
