LUL management have compiled an audit of distribution of Operational Standards Notices (OSNs). Although they claim it shows the system to be "robust", further reading reveals that in fact, OSNs aren't getting round to frontline staff nearly as efficiently and effectively as they should.
If this was just about some irrelevant bits of paper or management's latest propaganda sheets, you might be tempted to just laugh it off. But OSNs are absolutely critical to our safety. In fact, some of the more recent ones have been about tightening up our security procedures following the 7/7 bombings, what to do when train radio fails etc.
Our unions are rightly demanding that management address their shortcomings as a matter of urgency. In the meantime, if you are not confident in the safety procedures because your employer has failed to keep you informed and up-to-date, then remember your right to refuse to work on health and safety grounds.
