Anxiety is usually horrible at fast-paced places where it is normal to rush and you feel that you can't even take a breath to relax, that creates anxiety in itself. but dealing with egos and louder supervisors is difficult because they often become intense in that role. For instance you can have one manager/supervisor ask you one thing and the other supervisors/managers either disagrees with the previous manager or gives you conflicting requests/information. So it becomes a cluster of information that clashes, then you get yelled at so you have to be assertive and say "so this supervisor just said this; this is why i performed this said task". Then you think "should i mention that they said this".
Essentially if you can learn good assertiveness you'd be well on your way, but its not easy and that can be a complex thing.
Also training, i just think there are places you can work at where the training is poor, because they don't have the time to train people, you just end up figuring it all out through asking, trial and error, asking, watching, learning. But that can bring up safety and major error issues in my opinion.
Yeah you do it anyway, but alot of work places you will be anxious because the environment creates an anxious and unnaturally fast paced atmosphere.
I ask you this? After you finish at work, wherever that is, outside of that, at home, working on a personal project, even during education, fixing something in your own time, do you go as fast-paced as what you see at alot of businesses? No. You go at your pace, it natural, it flows, it's normal. But because there are so many products waiting to be made, sent out, the environment is just naturally uncomfortable and anxious enducing at work. It's not about the people and the comfort it seems, its about the product, its about KPIs, it about numbers and its about profits.
