The dependent variable of all regressions is output per worker-shift. WBT refers to the maximum wet bulb temperature on day of shift. Temperature daytime average refers to the average wet bulb temperature from 8am to 8pm on the shift day. Temperature 24-hr average refers to the average wet bulb temperature over 24 h on the shift day. Robust standard errors clustered at the worker level are presented in parentheses, and ***, **, *
