Your ability to stand for any length of time is all dependent on you. How well you can tolerate the pain, your ability to work through pt and if your doctors can get you to a point that you feel comfortable enough to stand for that long. For many of us here, standing for 8 hours is an unrealistic goal, myself included, but only time will tell.

I do not know how the employment laws are down in Louisiana, but up here in Michigan, your employer must make every attempt to find a position for you if you become disabled and are unable to do the duties of your previous position. Here in Detroit, casinos are unionized. Are they down there? If you do belong to a union, perhaps discussing it with your representative would be the thing to do. If you are not and you like your job, do not quit. Your employer can ask you to quit but can not fire you if you are making every reasonable effort to fulfill the tasks given to you, otherwise there are too many legal implications that they could potentially be faced with.
