Chief petty officer

The rating of Chief petty officer was the highest enlisted rating in Starfleet. The chief petty officer, invariably referred to as chief, was a senior non-commissioned officer and is often in control of an entire section of petty officers and unrated enlisted personnel.
:The term "chief petty officer" is deduced from real-world naval nomenclature; it is not used in canon Trek, only the word "chief".
Chiefs are further subdivided into a series of ranks based on seniority and merit. These ranks, from lower to higher are as follows: chief, senior chief, and master chief. 
While chiefs are subordinate to all commissioned officers, intelligent ensigns or lieutenants will listen to their chiefs, as these non-commissioned officers frequently have far greater experience than the junior officers under whom they serve. Even senior officers recognize the value of a good chief petty officer and will take their suggestions and advice seriously.
