Consistent adoption adoption of Open Educational Resources (OER) depends on a number of factors. These may correspond to business, legal, policy, academic or technology issues. Among the vast number of elements making deployment harder, one is often underestimated: an increase on the demand for teacher's time. Some solutions to motivate and/or gratify teachers that adopt OER have been proposed over the years and used successfully among the first adopters. Unfortunately, such solutions are not always possible in several contexts. In this paper, we propose that a key concern of research on OER technologies should focus on saving teacher's time when creating pedagogical resources.
