Facing the tai Sui for the year, is indeed a little undesirable. However, this is not "detrimental." so you need not worry. Furthermore since this is your working direction, means you can simply adjust the angle of your sitting slightly.
There is no such thing as "Compass School". All schools of Feng Shui uses a "Compass". Gua Formula belongs to the "Ba Zhai" system. It has two parts - the Life Gua (for personal directions) and House Gua (for house's sectors). Facing a good personal direction is beneficial. However, if you are "located" in a good sector, then even if you are facing your best direction, you can still enjoy positive Qi.
