Telling My Employer

I work as [Your Job] at [Employer Type] and I'm caring for my [Relationship] [Initials] ([Their Diagnosis]). What's happening at work: [What's Happening At Work]. What I need: [What You Need]. What my employer already knows: [What They Already Know]. Help me: 1) explain in plain English what FMLA generally covers for caring for a parent, who's eligible, and what intermittent leave means — as things to confirm with HR, not legal advice, 2) write a short, professional message to [Who You're Telling] that says what's going on and asks for one specific thing, without oversharing, 3) list the flexible arrangements worth asking for that cost the employer nothing, 4) tell me what to document and why, 5) give me a plan for the day I get a call at work that [Initials] has fallen. Tell me when to look up my state's caregiver leave laws, which may cover more than federal.
