Sr Engineers that want other to just do what they say with no context or explanation

You are probably right but just explain why!

the word "senior" has lost its respect these days, anyone above 2 yrs of exp wants to get called a senior. i am a junior at a company and not just me or my seniors, even the interns here are expected to have the most basic skills of "communication" and "teamwork"

Senior is someone who has the knowledge and expertise. I am in the field for well over 10 years and still learning. I can stop but laugh when I see someone with just couple of years experience and call themselves senior or worse an architect. Seen it all at this stage to be honest

Well. Then ask.

It is your right to know why and what's going on.

If they fire you for being pesky about understanding the mine field someone laid out at your front door, they probably aren't a healthy long term choice.
