things i’ve learned in the area:

be polite and have manners, even in emails. this will earn you respect, and people will want to talk to you.

communicate with your boss. if you’re unsure about something, don’t be afraid to ask. this shows that you care about your work and your job enough to voice any concerns or questions.

clear days off whenever possible - this shows responsibility on your part when you want a day for vacation or whatever.

be friendly! if people like you and respect you, chance are you won’t get bashed too hard if you ever make a mistake.

if you make mistakes, own up to them and fix them.
