Answer
A member in-good-standing is someone who has completed, signed, and submitted a PSAC membership application. This can be provided by the employer at the start of one's employment, supplied by a union representative like a Shop Steward or a Local President, or supplied by the union. The Digital Membership Application form is linked HERE.
If you are unsure whether or not you are a member in-good-standing, you can inquire by emailing [email protected] or by calling Membership Services: (867) 667-2331.
