text: what does a "thank you for giving me a heads up" mean? before i moved on with something i was working on, i confirmed it with my supervisor before consulting the matter to another higher-up. i thanked my supervisor for helping me out and she told me "thanks too for giving me a heads up". what did she mean by that? basically it means thanks for letting me know.  you gave her a head start or let her know that something is coming.
