There are two main groups of members: Ordinary Branch (OB) members are directly represented by the unions/affiliates and enjoy direct collective bargaining rights, while General Branch (GB) members, who work in non-unionised companies, cannot be represented directly but are given workplace advice and whose employment issues are still handled professionally. NTUC also works with social enterprises (see below) to provide a range of core and lifestyle benefits for all of its members. Since 2002, executives are also permitted to join the NTUC membership base, which was traditionally composed of rank-and-file employees. Apart from lifestyle benefits, they also enjoy some representation (if they are employed in unionised companies).
