According to estimates, 44% (3 300 million) of the total world population is employed, of which 26.5% (880 million) work in the agricultural sector. Statistics show that a larger share of people (up to 60 %) is employed in the agricultural primary production in the low income countries. Among the states of the European Union, the share of agricultural workers ranged between 0.6 and 21% with an average of 4.3% in 2019. The Czech Republic with 2.7% (141 thousand people) was below this average. In the period from 2012 to 2019, various data related to e.g. dairy farm worker numbers and labour costs were obtained from Czech dairy farms. On average, 13 workers per dairy farm were involved in dairy cow management, i.e. 49 cows and 402 thousand litres of milk sold per 1 worker. Labour costs averaged 10 thousand CZK per cow and year, i.e. 1.25 CZK per litre of milk sold. In the last three years, labour costs per litre increased by 8%. They were higher by 0.77 CZK in the farms with less than 200 cows compared to those with more than 999 cows. Dairy farms with the average milk yield above 10 thousand l had 29 % lower labour costs than those with the yields below 7 thousand l.
