FMLA is job protection and is not about pay. Not every job offers sick time. I don’t know what percentage of salary STD covers. IIRC FMLA is only applicable to larger companies.
People shouldn’t have to dig into sick time or take Short Term Disability after having a baby just to maybe get paid for a few days or weeks, maybe at 100% if they’re lucky.
I think that’s why you’d be hard pressed to find Daria in its original form too: music licensing.
