I'm like a broken record on this topic, but my truck never ever stays in the middle of the street, nor in places where it doesn't belong.....not even for a minute.
Now I understand that your area is a bit different and it is a tight street.....but oh well.....not your fault. Park the truck halfway down the block or more if needed in a safe spot where you are not obstructing traffic and upgrade your shoes for walking.
Put it in managements lap that you are being threatened out there and fear for your safety, and also need to park far away so you don't get injured or in an accident. I have no clue as to what your stop count is, but sounds like it can be cut by 50% or more if that truck is where it belongs. They couldn't say crap about it to you.
