I've never heard of group legal coverage.
What types of legal issues do they cover - like divorce, contract disputes with your plumber???
If its malpractice.....your employer should automatically be covering you for malpractice without any additional charge from you. If they don't cover malpractice for you....I'd really think twice about this company.
However, I carry my own malpractice as well & I wouldn't do it through my employer. It is through one of the national pharmacy organizations.
