Education for the floor — not legal advice. Examples use Ontario law. Confirm every deadline, remedy, and procedure against your own collective agreement and the law where you work.
What this module covers
When layoffs arrive, a small mistake in the seniority list can change who gets to stay. This module shows stewards how to check the list, trace the bumping rights in their own agreement, calendar notice and recall dates, and flag accommodation issues without assuming one sector's rules fit every workplace.
- Know: The difference between seniority lists, service dates, and classification rules; how bumping rights interact with skills/qualifications language; layoff and recall notice obligations under your collective agreement and applicable statutes; trial/familiarization periods when the agreement provides them; and that human rights accommodation can constrain bumping outcomes (see Module 3).
- Feel/Understand: Steady under pressure when jobs disappear; protective of members' privacy during displacement; unwilling to let HR's spreadsheet become the only source of truth without verification.
- Be Able To: Read an employer seniority list against CA definitions; sketch a bumping tree from contract language (not from memory); run Module 1 intake on a displacement file; flag accommodation collisions for human-rights analysis; and calendar notice and recall deadlines before they expire.
HR's spreadsheet is a claim until you verify it against the collective agreement.

How to use this module
Allow 32 minutes for the reading and self-test. Bring your collective agreement layoff, seniority, and recall articles; a recent employer seniority list (or a redacted sample); and a notepad. Read in a private space — bumping files often involve medical leaves, accommodation, and job loss.
Start with the list and the service dates, then test each possible move against the rights and qualifications in your agreement. Seniority Bumping has the sector worksheet and cascade examples; this module focuses on steward intake, notice clocks, and accommodation collisions. Use Module 1's grievance filter and FAR sheet before filing.
The resources under Further learning go deeper on list reading. Ontario's Employment Standards Act, 2000 (ESA) notice rules sit beside your collective agreement (CA) clocks, not instead of them.
💭 Reflection
A bumping tree drawn on a napkin is not a grievance file. Your job is to turn employer charts into dated, verifiable facts before the recall window closes.
1. Seniority Lists vs. Service Dates
Employers publish seniority lists during layoffs, recalls, and posting disputes. Stewards must separate what the list shows from what the collective agreement counts.
| Concept | What it usually means | Steward check |
|---|---|---|
| Seniority list | Employer snapshot of order within a unit, classification, or department | Is the list current? Does scope match the bargaining unit? |
| Service date | Date continuous service began for seniority purposes under the CA | Breaks in service, leaves, transfers — CA defines what resets the clock |
| Classification seniority | Separate ladders for FT/PT, job family, or pay band | The agreement may limit bumping to one classification |
| Departmental / facility seniority | Localized order when the CA says so | A college campus, hospital site, or municipal depot may be its own pool |
| Probationary / trial service | Period when seniority may not accrue or bumping may be limited | New hires and redeployed members — CA language varies |
List-reading discipline
- Identify the pool: bargaining unit, classification, department, or facility named in the layoff notice.
- Match each row to CA definitions: excluded categories (casual, student, term) should not appear; if they do, document it.
- Verify service dates: compare hire dates, transfer letters, and leave records; employers mis-code returns from leave.
- Note tie-breakers: some CAs use service date only; others add job-class date, rehire order, or lottery rules.
- Preserve the published list: PDF or screenshot with timestamp; lists get "corrected" after members react.
Most union training makes the same point: the list is a claim, not gospel, until you reconcile it to the CA and member records.
💡 Note
Seniority for overtime or shift pick may use a different rule than seniority for layoff. Never assume one article governs all.
❗ Warning
Accepting an incorrect list without challenge can lock a member out of a bump they were entitled to. Consequence: lost job or wrong position. Remedy: immediate written request for corrected list; preserve the flawed version; file grievance if recall window allows.
2. Reading a Bumping Tree (CA-Specific)
Bumping trees: who may displace whom, in what order — are specific to each collective agreement. Ontario public-sector agreements (colleges, hospitals, municipalities, school boards) use different cascade models. No steward should memorize one sector's chart as Ontario law.
Common tree elements (labels vary — read your agreement's wording)
- Primary bump: more senior member in a declared surplus classification bumps into a junior-held job they are qualified to perform.
- Secondary / reverse bump: junior member bumped out may bump into another lower classification if the CA allows.
- Surplus / displaced status: interim category with recall rights; rights differ by CA.
- Recall rights: order and window to return when work returns; often strict calendars.
- Supervisory exclusion: managers and sometimes lead hands sit outside the tree.
How to build the tree from the contract
- Read layoff article + seniority article + any bumping or displacement appendix together.
- Draw boxes: classifications affected → direction of cascade (up, down, lateral).
- Mark qualification gates at each branch (Section 3).
- Mark accommodation holds: jobs held under human-rights accommodation may be off-limits (Section 6).
- Compare your sketch to HR's chart; every mismatch is a question, not an argument yet.
Treat bumping as a procedure-first grievance: wrong order, wrong pool, or missed notice often wins before qualifications are fought.
❗ Warning
HR's PowerPoint cascade may omit trial periods, recall pools, or part-time rules. Consequence: members accept wrong placements. Remedy: demand the written bumping sequence citing CA articles; do not sign individual agreements until the tree is verified.
3. Bumping Rights vs. Skills & Qualifications Language
Bumping is not pure seniority. Most collective agreements require the senior member to be able, qualified, skilled, or capable of performing the bumped-into job — language matters.
| CA phrasing (examples) | Steward implication |
|---|---|
| "Qualified to perform" | Employer may test fit; union challenges objective standards |
| "Skills and ability" | Past performance and training records matter — gather them early |
| "Reasonable ability" / "with reasonable training" | Short familiarization may be required — see Section 5 |
| "Meets posted requirements" | Posting language may import credentials the member already holds |
Skills disputes stewards should prepare for
- Employer adds new requirements after the layoff notice — compare to pre-layoff job description.
- Selective enforcement: junior incumbents lacked the same credential when hired.
- Training refusal: employer won't offer CA-guaranteed familiarization, then claims unqualified.
- Past practice: years of members bumping into roles without a specific license.
Do not relitigate Meiorin or undue hardship here — that is Module 3. If qualifications screen out a member on a prohibited ground, flag accommodation analysis; do not argue qualifications alone.
📝 Practice
Highlight your CA's qualifications clause in yellow. Write one sentence: what evidence would prove our member meets it?
4. Layoff Notice Clocks & Procedural Discipline
Layoffs trigger parallel clocks: contractual notice, recall windows, grievance filing limits, and sometimes Employment Standards Act (ESA) minimums. Missing a clock can end a case before merits are heard.
Typical CA clocks (verify yours)
- Layoff notice to union: advance days or weeks before effective date; may require union meeting.
- Individual notice: separate from union notice; content requirements (seniority, bump options).
- Bumping election window: members may have limited days to choose bump targets.
- Recall period: set by your collective agreement. Lengths vary widely, so read the article.
- Grievance time limits: Module 1 filter applies; displacement grievances are often time-sensitive.
ESA layer (Ontario)
The ESA sets minimum notice of termination (or pay instead) and severance pay, and it treats a layoff that runs past the Act's temporary-layoff limits as a termination. Where your collective agreement gives a greater benefit on the same subject, the agreement applies instead of the standard. Stewards should know both layers exist. For members covered by a collective agreement, ESA rights are enforced through the grievance procedure, not by a complaint to the Ministry, so treat an ESA shortfall as a grievance. Bumping and recall themselves come from your agreement; the ESA does not create them. Refer severance, recall-rights elections, and week counts to servicing staff.
Procedural intake (Module 1 tie-in)
Run the 6 W's on every displacement intake:
- WHO: grievor, junior incumbent (if bumping), decision-makers, witnesses to notice meeting.
- WHAT: classification eliminated, job offered, bump refused, or recall ignored.
- WHEN: notice dates, effective layoff date, election deadlines, recall offer dates.
- WHERE: facility, department, bargaining unit scope.
- WHY: CA articles allegedly violated (open-door wording on grievance).
- WANT: reinstatement, correct bump, recall, make-whole pay — confirm which remedies your agreement provides.
💡 Note
Calendar every deadline the day notice lands. Stewards who "will get to it next week" lose recall grievances.
❗ Warning
Letting a bumping election deadline pass while waiting for HR to "call back." Consequence: member deemed to have waived bump rights. Remedy: same-day written election preservation; request extension in writing citing CA; parallel grievance if employer refused timely information.
5. Trial & Familiarization Periods (When Your CA Provides Them)
Some collective agreements grant a trial period, familiarization, or reasonable training when a member bumps into a new classification. Others are silent — then employer "probation" policies may not apply to bumped members unless the CA says so.
Questions to answer from your CA
- Does a bumped member get a defined trial period in the new role?
- Can the employer return them to layoff status during trial — and on what grounds?
- Does failed trial affect seniority or recall rights?
- Is training time paid at the higher classification rate?
Steward role during trial
- Document assigned tasks vs. job description.
- Attend return meetings if the CA gives union rights.
- Challenge subjective "fit" failures backed by no metrics.
- Separate performance management from layoff procedure — employers sometimes conflate them.
If your CA is silent, do not invent a trial length from another local's agreement. Ask servicing rep whether past practice or employer policy creates enforceable rights.
❗ Warning
Advising a member to "just try it and see" without reading trial language. Consequence: member accepts a failed trial as final. Remedy: pull CA trial article before acceptance; grieve procedural violations within time limits.
6. Human Rights Accommodation & Bumping Collisions
Displacement can collide with accommodation: modified duties, reduced hours, accessible workstations, or reassignment under human rights law. Module 3 owns primacy of human rights, the duty to accommodate, and RTW privacy. This section flags bumping intersections only.
Collision patterns
- Member in accommodated role faces bump from more senior worker.
- Employer offers bump target that cannot be performed with existing medical restrictions.
- Junior member in accommodation bumped out without individualized human-rights analysis.
- Employer uses layoff to end an accommodation without undue-hardship proof.
Steward rules of thumb
- Do not bump someone out of an accommodation without human-rights analysis — accommodation may survive restructuring if transfer is possible without undue hardship (Module 3).
- Medical privacy: share functional restrictions, not diagnosis, in meetings.
- Separate tracks: layoff procedure grievance may run parallel to accommodation failure grievance.
- No DIY Meiorin: point to Module 3 and servicing counsel; stewards identify collisions, not litigate BFOR at the lunch table.
Contract seniority does not automatically trump accommodation duties. OHRC Human Rights at Work explains the test; see Further learning.
❗ Warning
Telling a accommodated member "seniority rules, nothing we can do." Consequence: human-rights breach and DFR exposure. Remedy: pause bump; request accommodation review; document employer's hardship claim in writing; escalate to servicing rep.
7. Bargaining Unit Scope & Past Practice in Displacement
Bumping trees fail when the wrong pool is used. Stewards in Ontario see scope fights in:
- Multi-campus colleges: unit-wide vs. campus seniority; read the agreement's pool definition.
- Health care: program vs. facility pools.
- Municipal: department vs. corporate seniority.
- Split units: FT/PT, casual, and student streams rarely intermix.
Past practice evidence
- Prior layoff cascades in the same employer.
- Historical seniority lists showing pool boundaries.
- Letters of understanding on restructuring.
- Arbitration awards in your unit: other locals' awards are persuasive, not binding.
When HR imports a "standard" chart from another employer in the sector, your first question is: show me where our collective agreement authorizes that chart.
💡 Note
Seniority Bumping walks committee-ready examples; bring your CA to the guide — do not copy another unit's cascade.

The library technician cascade. HR announces three FTE cuts in Library Services at a multi-site college. They publish a unit-wide seniority list and a bumping chart that sends surplus technicians into Campus B junior roles — but your CA defines campus seniority within the classification. Member A (most senior at Campus A) was told they cannot bump a junior at Campus A because HR applied unit-wide order. Member B holds an accommodated half-time desk role modified for a back injury; HR says a senior clerk from another department will bump B out next week.
Apply (Member A): Pull CA campus seniority language (Section 7). Rebuild the tree for Campus A pool only (Section 2). Compare list service dates (Section 1). Calendar bumping election deadline (Section 4). Draft open-door grievance preserving recall and make-whole remedies (Module 1 / Module 8).
Don't apply: Do not accept HR's unit-wide chart because "that's how the last college did it." Do not miss the election clock while negotiating the chart.
Apply (Member B): Flag accommodation collision (Section 6). Request human-rights review before any bump — do not treat seniority as automatic trump. Gather functional restrictions already on file (Module 3). Parallel track: procedural layoff grievance if notice was inadequate.
Don't apply: Do not share B's diagnosis in the hallway to rally sympathy. Do not tell B to refuse all contact with HR — stay on procedure.
Second beat — qualifications fight. HR claims Member A lacks a software certification for the bumped role. Junior incumbents were never required to hold it when hired (Section 3). Document job postings and training history; demand reasonable familiarization if CA provides it (Section 5).
Practice drill
📝 Practice
Round 1 — List audit. With a redacted seniority list (10–15 rows), mark: wrong classification, service-date errors, missing leave adjustments, and pool-boundary questions. Write three written questions to HR citing CA articles — not opinions.
Round 2 — Tree sketch. From your CA layoff articles only, draw a bumping tree for one classification on paper. Compare to Seniority Bumping worksheet layout. List two places accommodation could block a branch.
Round 3 — Clock calendar. Given a layoff effective date, back-calculate union notice, election, recall, and grievance deadlines on a one-page calendar.

Common pitfalls
- One-size-fits-all tree: Copying another sector's cascade instead of your CA.
- List worship: Treating HR's spreadsheet as final without audit.
- Missed election clock: Waiting for a "fair" offer while deadlines expire.
- Qualifications amnesia: Forgetting junior incumbents lacked the same standards.
- Accommodation blind spot: Seniority slogans where human rights analysis is required.
- Mixed seniority rules: Using overtime seniority logic for layoff pools.
- Verbal bump deals: Side promises outside written notice and grievance file.
