One reason legs get sore is because of overuse and swelling. Raising your feet while relaxing at home will help to negate gravity and allow blood and lymph fluid to exit the lower legs and return into circulation. Taking your socks / nylons off will also help to reduce swelling, thus soothing them even further. Raising your legs at or above your heart level is good for promoting circulation. Use soft pillows to elevate your legs while laying on the sofa, but don't hamper blood flow by crossing your legs or ankles. Soaking your legs in a warm Epsom salt bath can significantly reduce pain and swelling, especially if the pain is caused by muscle tension. The magnesium in the salt helps muscles relax. Don't make the water too hot (to prevent scalding), but make it as warm as is tolerable the warmer the water, the more effective the Epsom. Don't soak in the bath for much more than 30 minutes because salty water pulls fluid from your body and may dehydrate you. If swelling is a particular problem in your legs, then follow the warm salt bath with an ice bath until your legs start to feel numb (about 15 minutes or so). Always remember to dry your feet thoroughly after a bath so as to prevent slip and falls. If you're walking long distances, maybe the stress in your legs is due to muscle strain. Mild muscle strains respond well to some light stretching because it relieves muscle tension and promotes blood flow. The three main muscles groups to focus on are your calves, quadriceps, and hamstrings. In general, hold stretches (without bouncing) for about 30 seconds. Do these three to five times daily, until the discomfort in your legs decreases. For a quad stretch while standing, brace yourself against a wall, flex your knee, and try to pull your foot such that your heel touches your buttocks. For a hamstring stretch while standing, bend over at the waist and try to touch your toes. Warming up and stretching your leg muscles prior to walking or any athletic activity may help prevent injuries such as strains, sprains, and muscle cramps. Non-steroidal anti-inflammatories (NSAIDs) such as ibuprofen or aspirin are short-term solutions to help you deal with tension, pain or inflammation in your legs. Keep in mind that these medications can be hard on your stomach, kidneys and liver, so it's best not to use them for more than two weeks on a constant basis. Dosage for adults is usually 200400 mg, by mouth, every four to six hours. Alternatively, you can try over-the-counter analgesics such as acetaminophen (Tylenol) to soothe your legs, but never take them along with NSAIDs. Be careful not to take medications on an empty stomach, as they can increase the risk of ulcers. Ill-fitting and/or excessively heavy shoes also contribute to tired and sore legs. As such, wear stable, lightweight footwear that suits your job, sport or activity. Aim for no more than a 12 inch (1.3cm) heel. High heels crowd the toes and create more tension in the calf muscles and Achilles tendons. If you're a serious runner, replace your shoes every 350500 miles (560800km) or three months, whichever comes first. Remember to always tie your shoes tightly, because loose shoes or flip-flops puts more strain on your lower leg muscles. Minor leg injuries such as shin splints are often caused by walking (or running) uphill, on uneven terrain or on hard surfaces such as asphalt or concrete. As such, alter your course and change the type of surface you walk on switch to grass or dirt, for example. Weight loss helps prevent a variety of musculoskeletal problems as there's less pressure put on the bones and muscles of the feet and lower legs. For most women, consuming less than 2,000 calories daily will lead to some weight loss every week even if you're only a light exerciser. Most men will lose weight at under 2,200 calories daily. Switch to lean meats and fish, whole grains, fresh produce and lots of water for the best weight loss results. Many overweight people have flat feet and tend to over-pronate their ankles, so choosing shoes with excellent arch support is crucial.

As mentioned previously, there are pros and cons to each option that need to be taken into consideration before making a decision. The major con to resigning is that you most likely will not be eligible for unemployment benefits. Some pros to resigning include: Being able to spin your reason for leaving positively. You do not need to say you were fired or asked to leave. The reason given for termination by your employer will be "resignation". You may be able to negotiate a severance package. The company wants you to leave and at this point you may have the upper hand in a way, even if you don't feel like that's the case. In exchange for you leaving peacefully, you may be able to negotiate a severance package to include a few months of pay and benefits. The pros to waiting to be fired can outweigh the cons if you need the unemployment benefits and feel you will be eligible given your circumstances. If you are fired for no reason of your own, you have a very good change to receive these benefits. Additionally, if you feel your termination is wrongful and/or discriminatory, you may be able to file a suit against this employer. On the other hand, the cons to waiting to be fired include: You may not eligible for a severance package. You may receive bad references if another company contacts this employer. Your reason for termination will be stated as "fired" or "terminated" and possible reasons for termination can be disclosed (based on company policy as mentioned previously). For example, "The employee was terminated due to gross misconduct". Based on your evaluation of the pros and cons to both options, you must make a decision and express this to your employer as soon as possible. If you took some time out to make your decision, you will have to request another meeting to include all members in the original meeting. During the meeting: Briefly explain whether you have decided to resign or stay. Keep your explanation simple and professional. Do not get overly emotional or angry. Be prepared to leave that day. The employer may not take any chances and open themselves up to any risk by letting a possible disgruntled employee stay on the premises. If you have chosen to wait to be fired, be prepared to be fired that day. Be prepared to move on once you have made your decision and notified your employer. Since you will be leaving your position one way or another, it is now time for you to prepare yourself for your next career move.
