I am going to Germany for three weeks. A month in advance I tried asking it off as usual. When I did, it told me it was too long of a time frame and I should consider an LOA. A GSA happened to be standing right there so I asked her if that's what I should do. She told me that I could break it up into 3 different requests and it should be approved, because that is what someone else had done. I did this and forgot about it until today. Today the schedule came out for the first week I will be in Germany. I am scheduled for 32 hours. Now I realize that my time off request wasn't approved, but now it is too late to submit an LOA request. I know I need to talk to HR, but they are never available to talk when I go in. How can I go about fixing this? And will they allow me the time off? Clearly I won't be available to work so what will they do for the hours I am already scheduled? PLEASE HELP.
