As for bars in Westminster…
– only thing the Tories didn’t sell off to let someone else make a profit. Wonder why not ?.
In the early 1990s the then Tory Gov passed legislation to force drug and alcohol testing on the railway industry. Tested (inc for traces of past use of illegal substances, not just ‘the present moment) at employment, and any change in role that is safety critical (eg drivers, signallers, controllers, etc etc).
Also random testing, and testing for anyone involved in a safety related incident.
Fail and it’s instant dismissal + barred from the industry for life unless there’s a fecken good reason + any prescription drugs declared before.
Thresholds are far more stringent than normal civvy life – eg alcohol threshold is 30mg/100ml vs 80 for drink-drive (30 being the level where natural fermentation etc can in the stomach can be the reason).
Someone I know tested positive for opioids – which were traced back to eating poppy seed buns before the test (was not sacked for that).
Need to roll that legislation to the Commons given they are making decisions that impact of millions and can (like with the covid clusterfest) cost hundreds of thousands of lives. Could send thousands of military to their deaths, etc.
