Mid June I applied for a new job, my mum passed away 2 weeks later and I went on compassionate leave for 6 days - I work 3 days a week. I got a doctor's note for 4 weeks today. The job I applied for have given me the job to start beginning of September. My current job requires 4 weeks notice. I'm not really sure what to do? I work for the NHS by the way. I also have annual leave booked mid August which was booked ages ago. Obviously I didn't know my Mum would pass away. Please advise
