Can a employee of a IT Consulting co take legal action against employer for negligence in providing insurance?

My friend is working for a Consulting company as a Consultant. For the health insurance coverage the arrangement was employer contributes half of the total premium and remaining half is deducted from my pay check.Last month when he requested his employer to add himself and my wife to the company insurance policy, they said they will add it effective from August 1. Subsequently, when they had to visit a doctor because of some medical condition,he called up the Insurance company to check my insurance Id card since he hasn't received them till date and to ask for any Id or the number for the medical visit and to his surprise they said his policy was not active.Then he contacted the company Aug 22 (by email) and again on Aug 23(by calling and left voice mails since they don't pick up the phone) and inquired about this saying that they had emailed him saying that his family is on the company insurance starting Aug1st. There is no response. Is there any legal course to take against employer?
