This article is dedicated to a current problem for both Environmental Law and Labour Law theory. On the one hand, general characteristics of labour contract (regulations, legal essence, content, contracting, parts, kinds) are evaluated, and, on the other, some environmental aspects of some parts of the legally-binding content of labour contracts. Attention is paid to some specific features of the workplace and labour function of separate categories of officers in the field of protection of specially protected natural areas, forestry, hunting and fish industry.
