CLEANING giant Spotless has been accused of bringing back WorkChoices-style agreements by forcing cleaners to sign deals that require them to give up a right to overtime pay.

Signed statements by the cleaners, who work in big Victorian shopping centres, say they were forced to sign the agreements with Spotless or be threatened with having their shifts cut.

A cleaner who did not sign an ''individual flexibility agreement'' said she lost $200 a week from a reduction in shifts. ''I felt tremendous pressure to sign the agreement,'' she said.

The cleaner, paid about $16 an hour, said the loss of the Sunday shift had resulted in a ''massive reduction in my income''.

In another signed statement, a cleaner claimed she was told, ''You must sign.''
