I'll keep it short 
I've been off for a year on maternity - now taking my accrued annual leave from last year. So technically 'back'.
My workplace is TOXIC and my mental health is in absolute tatters over going back. I was going to leave and then I found out I was pregnant so stayed to ensure I got paid mat.
I've been offered a new job (non nhs) and need to give 2 months notice. Im due to finish my annual leave next week and physically return. So been back a month.
My question being - can I go off sick and hand my notice in? I want to avoid having to pay back my maternity but I honestly can't face going back.
Will my annual leave of a month count plus 2 months sick to take me to my 3 months 'returned to work' so I don't have to pay it?
Please don't judge - im a mess.
