French to English Bus/Financial Human Resources Presentation on the history of a union to new employees in Québec

The text is a transcription of a training session on union history, with references to specific strikes and lockouts over the past years and with emphasis on all that has been gained and must be preserved in the collective agreement.

One participant says, "C'est qu'on est ***encadré*** par rapport à l'employeur. Ça nous apporte une certaine, une aide à faire respecter un peu nos conditions, nos conditions de travail." That's all the context I have.

I realize that "encadrer" often means to "supervise, manage," etc. But here it seems to me that it refers to the fact that union members are "in their own box" (as it were), i.e, organizationally separated from the employer. But not sure and would welcome suggestions/translations.
