I started a new job about 6 months ago, it's average pay and fits well with the hours. However there is very little guidance and a lot of the time the approach is "just figure out as we go" rather than deciding the process at the beginning, ironing out any problems then so we are able to meet deadlines rather than problems arising literally the day before a deadline. How can I politely say to my manager I just can't work like this it's causing anxiety
