Everyone is unkind to each other and no one steps in or stands up.
Just look at the Sandy Peggie stuff and it gives you such a flavour of the dog eat dog environment.
The pressure everyone is working under is immense and yet there is no leeway or compassion for omissions, mistakes or hesitations. It's very much a blame culture where everything has to be someone's fault.
It is often incredibly physical - 13+ hours of sheer physical endeavour with few if any breaks - depending on where you work and who else can cover your patients. You can't even go to the loo when you want (I've bled through my clothes on numerous occasions because you can even take a few minutes away from the floor). Any admission of being tired, wanting to sit down or have a break is seen as being "lazy" or looking to skive, including in pregnancy or when unwell. No one would willingly speak up for fear of being seen as weak....(It's not as overt as this, all unspoken)
Medicine is still hierarchical in places, with some senior doctors still having an image of being untouchable. If you want to question their prescribing or the plan they make for a patient then you have to be brave enough to withstand the potential rant or attempts at belittling you in front of colleagues and patients that will come.
The organisations that you work for will not support you - sickness is punished, there's no study or progression opportunities, you can't park or have to pay huge amounts to park, even if finishing at 1am no one cares that you've got to walk a long way in the dark to your car.
There are no refreshments supplied or available - if you want a hot drink you have to bring all constituent parts to work with you. If there's a disgusting fridge to put your own milk in, there may be no mugs or spoons. Many NHS places have no real food provision and if they do it's not open to fit with shifts, a long way from work zones so you don't have long enough to get there and stand in the queue with everyone else, and pay stupid prices for something horrible anyway. You are not allowed to drink in front of patients so no breaks means no drinks, even if you are on for 12 hours and it's a heatwave.
There's no choice over what to wear, even if you are far too hot or cold at work. You can't control the environment - no way to cool it in baking conditions while you do a very physical job, or to heat it in winter when it's cold.
Very few areas have good equipment with which to do your job so you are expected to buy and supply your own - things like pen torches, watches, scissors, tourniquets etc.
If you raise any sort of concern or issue you are seen as negative, moaning, unable to take it or a trouble maker. No one will support you even if they think the same as you. No manager will believe you or give any weight to your opinion.
Absolutely everything about all the above sends the message that you are not valued, not respected, not important, every single shift.
