I work for a small company owned by three directors so no HR department other than them. It’s a regular occurrence for them to go for a few pints on the way home from work, have a few drinks at lunchtime or go on an all-night session till the early hours then drive.
I can’t sit by and watch this happen but can’t see any way I can prevent it either, other than calling the police each time it happens or resigning. I hate that I’ve been put in this position and coming up to Christmas it will increase as they have various customer/supplier dos coming up.
