health and safety

A Foxconn spokesman (which makes iPhones) encourages employees to keep conversation to a minimum for health and safety reasons.

Keep toilet breaks to a minimum. It's only a fourteen hour day and this encourages continence.

Keep suicides to a minimum. They are bad for company morale and effect profit margins.

Keep rioting to a minimum. Please don't talk whilst rioting. This encourages bad behaviour. You have nine seconds before the next component part to vent your feelings. This can be done with raising your eyebrows, saving your voice additional strain and keeping your skin tone supple.

Nobody can argue with health and safety reasons.
