where i'm working, usually when people leave their contract is replaced like for like with someone else.
but now as people leave (we have a big turnover of staff) they are only giving 8 hour contacts to new employees!
which is they say saves them on sick /holidays etc...
but this is no good to most people especially as it will be 8 hours over any 2 days out of 7..
ideal for students and school leavers i guess..
but more and more places seam to be doing this...
