Hmmm....I think at this point, instead of trying to appease others in the office (since they obviously don't appreciate it) I would decide what I want and go from there. Stand up for you as you certainly deserve to do so. You can always keep in the back of your mind that you would be flexible, but they don't need to know that....just voice what flex time you want to take and go from there. Let them work around it
