In reply to The Lemming:
Tbf I think it's especially bad in many parts of the NHS, where chronic understaffing, lack of resources, and poor planning over many many years have created a service which just can't cope with the level of demand and of course the people working on those environments will be put under a huge amount of pressure.
A silver lining for ambulance staff though is that at least they only have one patient to deal with at once (apart from the ones sometimes deployed to watch patients queued up from ambulances before they are admitted), so are only overworked in terms of missed breaks etc. Nurses pressured into working on understaffed wards for example face being responsible for large numbers of patients all at once and not being in a position to look after any of them as well as they'd like, all the while worrying that if something goes wrong they'll be the ones on the hook. Or, to pick a less popular example, mid level hospital management staff who can have massive workloads piled on them and are put under a huge amount of stress, even if that stress may have different qualities to that which frontline staff face.
I'm not sure many other workplaces are quite like the NHS in this regard though.
