So do several countries, as listed here at https://www.etuc.org/en/pressrelease/climate-crisis-requires... :

> Belgium: 29°C for light physical workload, 26°C for a moderately heavy physical workload, 22°C at heavy physical workload and 18°C at very heavy physical workload

> Hungary: 31°C for sedentary and light physical work, 29°C for moderately physical work and 27°C for heavy physical work

> Latvia: Maximum working temperature for indoor work of 28°C

> Montenegro: Maximum working temperature for outdoor work of 36°C

> Slovenia: The air temperature in work areas must not exceed 28 °C

(although I don't see any obvious similarities between the countries that do and don't have such protections, but based on that list it does seem that former Yugoslav and Soviet states are overrepresented)
