The reason they go in so cheap is to ensure they always get the contract.
Once won they move the goalposts.
If its window cleaning they send two men when the tender promised four then they reduce the cleaning cycle,instead of every four weeks it goes to monthly then miss a month as it was raining the time they came to do yours They also clean the window once ie using a very slightly damp applicator they wipe across the glass then blade it ,never, never detailing the edges never mind touching a frame and if there are still dirty marks smears etc they ignore them as they have "cleaned " the window.
I have watched them at Tesco stores, they do not even take a bucket out of the van and never ever clean above head height. It is so embarrasing to call them window cleaners.
When winning cleaning contracts in-store they employ the famous ghosting tactics. Instead of having the agreed amount of workers described at tender they allow the numbers to dwindle through "natural waste".First week of contract they do an excellent job passing all checks with flying colours, the supermarket boss is satisfied and thats that.
End of second week workforce reduced due to "unacceptable references" this way they get rid of at least two people,end of month they muck up the wages this moves on the next few and on and on. They never replace the staff that have left yet continue to charge for a full workforce, this then leads to the rest having to work twice as hard ,do twice the work and only get paid the normal. No overtime no bonus no thank you payments.
They then get fed up and move on. This is when the real clever bit starts. The cleaning company aggressively advertise for staff, really impress the supermarket how hard they are trying and because everyone in the town knows how horrible they are to work for they only get the wasters applying, allowing the cleaning company to moan that its impossible to find any decent staff in this area so they employ the ragged the hopeless and the ones forced by the job centre to apply,obviously they are hired,fired moved on and round we go again.
But the supermarkets are so impressed with the " we are short staffed but will still get the job done atitude" that they will never lose the contract.
So they win it cheap ,lose half the workforce and rake it in on saved wages still charged at full amounts.
Don't believe me ? why then did the Houses of Parliaments cleaning staff employed by M*"*E go on strike? not for more wages but for the true staffing levels to be filled as they were working too gard too long for nothing extra.
Go and watch the window cleaners see for yourself or look at the state of the windows, now there may be an exception to this rule but normally all Tescos cleaning are supplied via one contract done at head office , but if there are independants out there i apologise and compliment them but watch out those ghosts will get you
