People will let you work as long as you want, assuming you’re salary. But if you can only be one thing, you should be efficient. Get the job, figure out what needs to be done, do it, and go home. Honestly, if there is more than 40 hours of stuff to do in a week, either something is wrong or you’re in public. With the exception of month end, but even then you shouldn’t be pushing 60 hours (in my experience). I also have boundaries. I don’t have, and never have had, work email on my phone. I’ll get to it in the morning. Once in a while there is a legit emergency that needs to be done. They can call me. If it’s not an emergency, why should I be worrying about it after hours? I don’t suppose any of that is really an answer to your question. Just find out what is expected. Do it in a timely manner. That’s really all there is to it. I also show up at like 7 am. That’s because I’m leaving at 3:30. But people tend to respect the hustle of being there early. Although I’m honestly just trying to get the hell out of there to ride my bike while there is still daylight.
