, the MBTA employs 6,346 workers, of which roughly 600 are in part-time jobs.

Structurally, the employees of the MBTA function as part of a handful of trade unions. The largest union of the MBTA is the Carmen's Union (Local 589), representing bus and subway operators. This includes full and part-time bus drivers, motorpersons and streetcar motorpersons, full and part-time train attendants, and Customer Service Agents (CSAs). Further unions include the Machinists Union, Local 264; Electrical Workers Union, Local 717; the Welder's Union, Local 651; the Executive Union; the Office and Professional Employees International Union, Local 453; the Professional and Technical Engineers Union, Local 105; and the Office and Professional Employees Union, Local 6.

Within the authority, employees are ranked according to seniority (or "rating"). This is categorized by an employee's five or six-digit badge number, though some of the longest serving employees still have only three or four-digits. An employee's badge number indicates the relative length of employment with the MBTA; badges are issued in sequential order. The rating structure determines many different things, including the rank in which perks are to be offered to employee, such as: When offering the choice for quarter-annual route assignments ("picks"), overtime offerings, and even the rank to transfer new hires from part-time roles to a full-time role.
