Master Seniority List Review

 

Dear Local 531 Members,

 

Every year, no later than September 1, the Company must post a copy of the Master Seniority List on SharePoint for all members to view. 

 

This year, the list was posted by the Company on September 1, 2026, and will remain open for review until September 30, 2026.

 

 

Your Responsibility

 

It is each member’s responsibility to review the list and ensure your bargaining unit seniority is correctly reflected. If you believe there is a discrepancy in your seniority, you must submit a written request for review to both:

The deadline to submit your request is September 30, 2026. Written requests will only be reviewed if sent to the contacts above.  

 

 

RSA & RSC Bargaining Unit Integration - Important Notice for RSLs!

 

If you have held a Ramp Service Agent or Ramp Service Coordinator role at anytime beginning September 1, 2022 and moved into another bargaining unit role prior to March 1, 2025, your seniority on the Master Seniority List may be incorrect if missing this credit. It is imperative that you submit your dispute as early as possible using the instructions provided above.

 

 

Why Seniority Matters

 

Seniority plays a key role in:

  • Schedule bidding and changes

  • Shift extensions

  • Company-offered VTO before schedule build on statutory holidays

  • Removal of shifts from the pool

  • Awarding voluntary unpaid personal leaves

  • Filing vacancies

  • Vacation bidding and awards

  • Layoffs and recall

Why is There a Master Seniority List?

 

The Collective Agreement requires that all members covered under it are placed on a single, unified seniority list.

 

This is important because:

  • One bargaining unit – Even though our members are spread across Calgary, Vancouver, and Toronto, we are all part of the same bargaining unit. Seniority rights apply to everyone equally, regardless of location.

  • Fairness and transparency – A master list ensures there is no confusion or unequal treatment between bases. Everyone’s seniority is tracked and applied consistently across the country.

  • Movement between locations – If a member transfers from one base to another, their seniority follows them. Having one master list prevents disputes about where they “rank” after moving.

  • Application of rights – Seniority affects many rights under the CBA (vacation awards, layoffs and recalls, schedule bidding, shift extensions, etc.). A unified list ensures these processes are based on the same standard for all members.

The master seniority list ensures consistency, fairness, and transparency across all three locations, since we are one Local and one bargaining unit under the Collective Agreement.
