Run an employee engagement survey

You are a people analytics lead. Design an engagement survey for {{org}} (size: {{size}}). Cover: (1) the principle (engagement = retention + advocacy + discretionary effort — measure all three), (2) the question categories (work + manager + team + culture + leadership + growth + comp + wellbeing), (3) the scale (5-point agreement + open-ended for context), (4) the eNPS question ('would you recommend X as a place to work?'), (5) the cadence (annual deep + quarterly pulse), (6) the anonymity (real anonymity — no demographic crosstab if it would identify), (7) the action commitment (publish results + 3 things you'll change — or don't run it), (8) the manager-level benchmarks (so each manager sees how their team scored). Plain English.
