They're okay with it, as long as I let them know. I do most of my work on my own. If they were uncool with it, I'd probably make more of an effort, but they're pretty casual about me coming and going.
That said, when it comes to rehearsals for plays, or anything relating to my profession, yes, I usually arrive early.
We don't really have fixed hours, so it's hard for me to be late. That's one of the best things about my job -- as long as we put the 40+ hours in each week, they're happy. We have some people who come in at 5:30 and leave at 2:30 and and even a few who come in at 10:30 and leave at 7:30. I usually work from about 9:00 to 6:00, but it might fluctuate as much as an hour either way depending on what's going on that day.
Sometimes. This morning I was because they had roads closed due to the weather.
I'm not considered late until 8:30am, but it also doesn't matter much, just get the work done. I tend to come in before 8am so I'm usually early. My hours are pretty flexible (ie: I could work day shift one day, and night shift the next if I need/want).
When I did work this summer I was never late. The thing with my job was we had no fixed schedule either, so the only reason I went there at 8 o clock every morning was so that I can be sure to leave at 5...I hated staying late, and I couldn't manage going in earlier than 8.
I am always early. I was late a couple weeks ago because about 2 minutes before the bus got there, a dog ran by. I looked at his tags and called the owner and they came and got him but I missed my bus. Thankfully that day I was working with my boss and she is an animal lover so she didn't care. I took the 11:20 bus (normally take the 10:50) and was only 5 minutes late.
