Oh, I didn't realize there were comments. Here is "more than meets the eye":
In the past two years, he has set foot in our laboratory a total of four times. He only signs purchase orders. What do I do? Yeah, I make media, components, a few ingredients to be used in the actual experiements. He goes on vacation so there's no way to get stuff we need -- these three months during summer I put in 0 hours of work besides checking in and asking if there was anything to do -- i focused on volunteering and etc. So when I say 5-10 hours a week, that's really quite loose. But then there are weeks where all our purchases come in and I'm doing roughly 7 hours a few days in a row, like I did last Weds-Friday.
He is hit or MISS in this regard. Mostly miss.
About the publications: if they are using the products I made then I feel I should have some acknowledgement or authorship in the paper, ESPECIALLY if I get data points that are used in the paper. I wouldn't care about which number author--obviously not 1st--but yep. It's not a big deal, I can mostly write this off. About the LOR - I've gotten over it. I went by his office hours, his door was closed. So long and farewell! I've been in another lab since June and it's been sublime; averaging about the same time put in but it's with animals so i'd say it is a bit more significant.
