Before I sign up for medical insurance?
How much does it cost to have it? Should I or should I not sign up for it?
Answers: Well your employer should enjoy an employee benefits handout that you should probably achieve from the HR department. If you work full/part time see what comes out of your pocket. Some companies have it to where on earth if you work full time you wont get charged, some still charge you depending if you enjoy a PPO/HMO etc.
Well you need to ask them at work how much it costs. All policies are different. If you don't own insurance and you can afford it then you really should sign up. You never know when an accident could evolve or you could be diagnosed with a serious bug or disease.
