Annual US work stoppages (strikes and lockouts involving 1,000+ workers, one full shift or longer) from the BLS Work Stoppages bulk files (keyless): one row per year, 1947 to the latest complete year, with stoppages beginning, workers involved beginning and in effect (thousands), days of idleness (thousands of workdays) and days idle as a percent of estimated total working time. Method: the six BLS measures are pivoted from annual (M13) bulk rows into a wide year panel; footnote-2 censored percent cells and footnote-1 unavailable cells are kept as honest NULLs with flags, preliminary flags preserved. Derived signals: days idle per worker, workers per stoppage beginning, and a trailing 5-year average of days idle. Units: days_idle_000s and workers_*_000s are in thousands; *_pct is a percent. Caveats: not comparable with the pre-1981 series that covered 6+ workers; the percent-of-worktime series was archived by BLS after April 2024 (NULLs from 2024 onward, never imputed); in-effect measures exist from 1981 only.
Monthly US work stoppages (strikes and lockouts involving 1,000+ workers, one full shift or longer) from the BLS Work Stoppages bulk files (keyless): one row per month, 1981-01 to the latest published month, with the six BLS measures — stoppages beginning, workers beginning, workers in effect, stoppages in effect, days of idleness (thousands of workdays), and days idle as percent of estimated working time. Method: monthly bulk rows pivoted wide; censored/unavailable cells kept as NULLs with flags; preliminary (footnote P) months flagged. Derived signals: trailing-12-month averages of days idle, workers in effect, and stoppages in effect, plus year-over-year percent change in days idle. Units as the annual panel. Caveats: updates land ~3 weeks after month end; monthly figures are preliminary until BLS issues final monthly + annual figures in February; the percent-of-worktime series was archived by BLS after April 2024 (NULLs thereafter, never imputed).
