RMT confront ISS agency over lockout

RMT members supported by the National Shop Stewards Network go to ISS corporate headquarters in Canary Wharf.
ISS has imposed fingerprinting and biometric scanning on their workforce of cleaners on the London Underground.
After a lawful ballot for industrial action RMT ISS members have refused to comply with the scanners when clocking on to work. In response ISS have sacked one cleaner and sent others home.
The RMT went to ISS HQ to demand answers for this behaviour.
