Basically I'm at the last stage of the article review process. We've already been through 2 rounds of copyediting (after the peer review stage), which none of my supervisors read as they trusted me to do the donkey work. (I don't blame them).
So far I've asked them to notify me at every stage of the review process, which has slowed down the process as I've had to wait for all 3 supervisors to confirm they are happy before I send off the article for another round. At this last stage I have read the paper thoroughly and can't find any issues and am keen to get it published asap. Am I still obligated to get my supervisors' approval at this stage, or should I just send it off?
I'm asking so I know the etiquette for future papers as well - I don't want to waste my (and my supervisors') time any more than necessary.
EDIT: all of the supervisors are on the authorship team.
