don't blame the block cleaners for sitting in there vans all day they have a job to do and they do it ,it is not their fault that the supervisors don't check up on them.
low pay for them so they just do as they are told, if they not given enough work too do they sit down be it on a stairway or in the van where it is warm.
they are not paid to think or use their own initiative.just clean what they are told too clean
if you have something to moan about ,moan about the supervisors and managers of the block cleaners they are the lazy ones on obscene amounts of money
