I work in an area of expertise which is wide reaching. Depends on projects you work in to define the experience you get😊. I recently moved from one area back to another area which I’ve been out of for 2.5 years. I received a request to review something that I’m not an expert in and there is an impossible deadline. If I had time to research I’d be ok but I don’t and the client wants a response yesterday. Should I highlight to my boss I don’t feel comfortable in such a short timeframe to do what they need or try and do loads of research in short space of time? I’ve been given difficult projects already so feel v much under pressure with no time! I’ve only been back in this area for 3 weeks so feel overwhelmed with this request but don’t want my work to think I can’t do the job?
