its not 40K + plus rent, its 40k only per month.
At the moment on I'm 34K per month with subsidised rent. Serco provide me with 3 bedroom apartment 75K pa, market rates would have me paying between 120-150K pa.
I figure 1 overtime per month puts me pretty close to the GCAA guys, given also that they are on 45 days annual leave and I get 56 days with Serco.
Unfortunately I cannot see Serco moving too quick to improve this package in the near future.
Think long and hard chaps if you're coming here for the money.
