Still there- I'm in a senior role, and am trying to change things. I am lucky to work with some lovely people, both within the nursing team and wider MDT. Most of us seem to be working towards a more integrated team. This is why I stay, as I feel there is motivation and work happening to improve things. I also still love critical care nursing, and enjoy the (sadly few occasions) when I am allocated to the bedside.
The 'not talking' where I am seems to be more down to a large number of junior staff trying to balance their workload and find their feet, and the layout of our ward with small bays and side rooms, which make it difficult to leave the room sometimes. Also, it can be difficult to integrate in to a larger team, and this is a common comment from nurses who come to us from smaller teams.
The bigger knock-on effect of a more inexperienced workforce also seems to have have pushed us back towards a more hierarchical structure again. Although the senior nurses and medical team have been trying to support the bedside nurses to become more autonomous, the bedside nurses don't have that confidence yet. This is then becoming the culture, and our new starters were noted to be picking up this way mindset, hence the work to improve this.
When I'm on duty, I do my best to get round to everyone, check on the patients and offer help and advice to other staff. I am finding that I am being asked for more help, and often with more 'basic' tasks or issues, than ever before. I am of course willing to help them, I think it reflects the deeper issues withing the NHS generally at the minute.
At the same time, the workload for managers is getting larger and us more experienced critical care nurses are still somewhat beaten and bruised after 3 years of pandemic nursing. I can easily imagine that this has manifested as stress, with some managers burning out and behaving poorly towards other staff. I am not for one moment suggesting that this acceptable, nor that it was never a problem pre-covid, but I do think it explains why this is such a widespread problem at the moment.
Sorry for the ramble- my overall advice to you OP is that you do need to think of yourself and your needs first. Nursing is a very diverse field, and you may in future find a critical care area or role that fits you much better. At the moment, you sound like you need a change. I would have a look at other opportunities and see what is the best fit for you.
May I also advise speaking with a counsellor if you haven't done so- critical care nursing is already a very stressful job (lots of death, very distressed families) and you've also had to deal with a toxic workplace- you can self refer through occ health or through your union, if a member. I wish you the best of luck, whatever you decide to do next
