Problem with Social engineering

I was thinking about the Family Medical Leave Act the other day. Although I imagine many people might have problems with me questioning the great social policy that it is, I'll just throw out there an example of the abuse that it brings. What occurs is that employees only have so many sick days (let's say 12 in a year). Once those 12 are used up they can only take unpaid "Family and Medical Leave." To use this properly, an employee must either be significantly ill or a family member significantly ill that they need at the minimum 3 days off. What ends up happening is that they either out right say to their employer they need 3 days off or lie and profess sickness for 3 days even though they want 1 or 2 days off for whatever reason. Happens all the time in government and I imagine in the private sector as well. Liberal politicians are always abused and people will always find a way around the barriers set up to prevent abuse.
