Unfortunately, everyone heals differently and every fracture is different. It usually takes about 6 to 8 weeks for the bones to heal, then the soft tissues have to be rehabilitated.
If there is going to be a problem with standing, usually it is due to swelling. So, it is recommended that you wear compression stockings and try to take frequent breaks to get the foot elevated.
As to when you should return to work, that is something you should ask your surgeon. Good luck.
