Which I really wouldnt mind at all really! I love being off and it would make explaining to DH that I dont want to go back!
Ive just seen on my works job page, my job. Same job desc (I know because I wrote it and it has reference to a committee which is now broken up) The only difference is that it now says 'Admin' instead of 'Senior Admin'. The pay is the same and it makes no reference to being maternity cover. I know if it were for my mat cover, it would say as the lady covering my maternity left and i saw the readvertised position that time.
Add to that my manager has just hidden her FB page from me.... 
Im for the chop, I think!
