I'm applying for a job relevant to something I did over 10 years ago and would like to get back into. My boss at the time (back in 2008!) thought very highly of me but I haven't been in touch since I asked her for a reference in around 2010 (which she was happy to). Is it strange if I contact her now and ask if I can put her as a reference again? She's very high up in the industry I want to get back into and would be a great reference. I've found her on linked in. So AIBU to contact her?
