I'd rather the cubicle door wasn't wedged open when I'm trying to have a shit thanks.
What about front doors to buildings or offices, or keypad entry. Not everywhere can just leave doors open whether for security, or fire safety reasons.
What if the job involves a lot of having to walk down the narrow corridor or walkway, waiting would cut your productivity by 40 or 50 per cent but the boss just pushes and harangues you to keep your working rate up?
And above all how can measures magically be implementable in a workplace but somehow uncomprehensively difficult to implement or follow in a private home?
