Raul and Ranjnish:
You both make excellent points.
Raul, I see some problems with an hourly based contract for a health care provider, especially if you are referring to a medical doctor.
* Are you willing to guarantee a number of hours?
* Where will the employee be seen? Who pays cost of travel?
* What will you pay for fractional segments (less than an hour)?
* Will you be willing to pick up the administrative costs, i.e. recordkeeping and billing?
I think there are other ways to implement wellness programs that are almost cost free. For example, the Blood Bank will do blood pressure screening for employees and dependants when they donate blood. (The Bank will be glad to send a van to your location). The Diabetes Association will do screenings.
Contact local healthcare agencies for guidance, support and contacts. If you have a Plant Nurse (s)he should have some ideas.
In addition to providing preventative programs (forgot to mention annual checkups, thanks Rajnish), also consider subsidies for health club membership, or set up small "workout room" in the facility which should be accessible to employees and dependants. {Check with legal to assure that the company is not exposed to any liability in the event an employee/dependant is hurt in the "workout room". Membership based on dues of $1.00/year for each participating member may be the best route.}
Further, you could send press releases to local news media to publicize the Company's efforts to hold down healthcare costs, thereby demonstrating that the company is considerate, compassionate, and responsive to employee needs, as well as being a responsible member of the community.
