Discipline, grievances and arbitration

Most workers on a construction site never face discipline, and most supervisors would rather never impose it. But sooner or later a supervisor has to deal with a worker who is repeatedly late, ignores a safety rule, damages equipment, harasses a co-worker or simply cannot do the work. How the supervisor handles it decides whether the problem is corrected, whether the crew sees the response as fair, and whether the decision survives a grievance or legal claim. This lesson covers the principles of fair discipline, how grievances and arbitration work in unionized construction, and the different rules that apply to non-union workers.

The purpose of discipline

Discipline in a well-run workplace is corrective, not punitive. Its purpose is to make clear what standard is expected, give the worker a fair chance to meet it, and protect the crew and the work. Punishment for its own sake breeds resentment and rarely changes behaviour. That is why labour arbitrators, and good supervisors, look for progressive discipline: a sequence of increasingly serious responses that gives the worker notice and an opportunity to improve, except for misconduct so serious that it justifies immediate dismissal.

Some conduct can justify skipping steps: violence, theft, serious harassment, deliberately disabling a safety device, or working while impaired in a safety-sensitive job. Even then, the employer must investigate, give the worker a chance to respond, and consider the circumstances before deciding.

Just cause in Canadian labour arbitration

Almost every collective agreement says that employees may be disciplined or discharged only for just cause. Canadian arbitrators apply a three-part test set out by the British Columbia Labour Relations Board in Wm. Scott & Co. (1976): first, has the employee given just and reasonable cause for some form of discipline; second, if so, was the employer's response excessive in all the circumstances; and third, if it was excessive, what alternative measure would be just and equitable? Arbitrators in every province can substitute a lesser penalty, and they often do.

In deciding whether a penalty was excessive, arbitrators consider factors such as:

• The seriousness of the conduct and its effect on safety, co-workers and the employer.
• The worker's length of service and disciplinary record.
• Whether the conduct was a momentary lapse or premeditated.
• Provocation, personal circumstances, and whether the worker acknowledged the problem and apologized.
• Whether the rule was known, clear and consistently enforced, including against other workers.
• Whether the employer followed its own procedures and the agreement's requirements, such as notice to the union.

Consistency is where employers most often lose. If Luis suspends one carpenter for not tying off at the slab edge but a foreman let another carpenter off with a word for the same thing last month, an arbitrator may find the suspension discriminatory or excessive. Calder Ridge's discipline records are kept centrally by Grace so that supervisors can check how similar cases were handled.

Investigating before deciding

A supervisor who disciplines first and investigates later is likely to lose at arbitration and, more importantly, may punish the wrong person. Calder Ridge's investigation steps are short but required.

• Get the facts: what happened, when, where, who saw it; photographs and documents.
• Interview the worker, with a steward present if the agreement provides for it or the worker asks, and hear their side.
• Interview witnesses, separately where possible.
• Check the worker's record and how similar cases were handled.
• Decide, considering the factors above, and record the reasons.
• Tell the worker the decision and the reasons, in writing, with a copy to the union where required.

Where the conduct creates an immediate risk, such as suspected impairment or violence, the worker can be removed from work with pay pending the investigation. The decision on discipline comes afterwards.

The grievance procedure

A grievance is a formal complaint that the employer has violated the collective agreement. It can be filed by a worker, by the union on behalf of a group (a policy grievance), or sometimes by the employer. Ontario's Labour Relations Act requires every collective agreement to provide for the final and binding settlement of differences by arbitration without a work stoppage, and construction agreements set out steps and time limits for getting there.

Construction moves fast, and waiting a year for an arbitrator does not suit a project that will be finished by then. Ontario's Act allows either party to a construction collective agreement to refer a grievance to the OLRB, which appoints an arbitrator or hears it itself and must begin the hearing quickly. Many construction agreements also provide for expedited arbitration or joint committees. These faster routes are one reason construction grievances in Ontario tend to be resolved within months rather than years.

Most grievances are settled long before arbitration, usually at the first or second step, and the best way to settle them is to deal with the issue early. Luis expects his foremen to talk to the steward when a worker is unhappy, before anyone writes anything down, and to call Grace as soon as a written grievance appears.

Managing time limits

Grievance procedures have strict time limits: a grievance must be filed within a set number of days of the event, and each step must be answered or advanced within a set time. Missing them can cost a party its case, although arbitrators in many jurisdictions have some power to extend limits where the delay caused no real harm. Grace tracks every open grievance in a simple log.

# Open grievance log with days to the next deadline (as of a review date; illustrative)
from datetime import date, timedelta
today = date(2026, 10, 19)
grievances = [
    # (id, subject, step, date of last action, days allowed for next action, who acts next)
    ("G-14", "overtime distribution, forming crew B", 1, date(2026, 10, 12), 7, "Calder Ridge (step 1 reply)"),
    ("G-15", "show-up pay, wind cancellation", 2, date(2026, 10, 2), 14, "Calder Ridge (step 2 meeting)"),
    ("G-16", "3-day suspension, fall protection", 2, date(2026, 10, 9), 10, "Calder Ridge (step 2 reply)"),
    ("G-17", "apprentice wage step not applied", 1, date(2026, 10, 15), 7, "Calder Ridge (step 1 reply)"),
    ("G-12", "subcontracting of acoustic ceilings", 3, date(2026, 9, 1), 30, "union (refer to arbitration)"),
]
for gid, subject, step, last, allowed, who in sorted(grievances, key=lambda g: g[3] + timedelta(days=g[4])):
    due = last + timedelta(days=allowed)
    left = (due - today).days
    status = "OVERDUE" if left < 0 else ("due this week" if left <= 5 else "")
    print(f"{gid} step {step}  due {due}  ({left:+3d} days)  {who:30s} {subject} {status}")

G-12 step 3  due 2026-10-01  (-18 days)  union (refer to arbitration)   subcontracting of acoustic ceilings OVERDUE
G-15 step 2  due 2026-10-16  ( -3 days)  Calder Ridge (step 2 meeting)  show-up pay, wind cancellation OVERDUE
G-14 step 1  due 2026-10-19  ( +0 days)  Calder Ridge (step 1 reply)    overtime distribution, forming crew B due this week
G-16 step 2  due 2026-10-19  ( +0 days)  Calder Ridge (step 2 reply)    3-day suspension, fall protection due this week
G-17 step 1  due 2026-10-22  ( +3 days)  Calder Ridge (step 1 reply)    apprentice wage step not applied due this week

On the review date, the log shows problems on both sides. G-12 is 18 days past the union's deadline to refer the subcontracting grievance to arbitration, which Calder Ridge may be able to rely on. But G-15 is three days past Calder Ridge's own deadline for the step 2 meeting, so Grace called the business representative that morning to apologize and set a date, rather than give the union a reason to argue that the company had forfeited its position. G-14 and G-16 are due today. G-17 is the kind of grievance Calder Ridge should simply settle: if the apprentice qualified for the higher wage step, the company owes the difference and should pay it promptly, which also builds credibility with the union for disputes that are genuinely contested.

A discipline case from Elmwood

In month 9, the safety coordinator found a carpenter with eleven years' service working at an unprotected slab edge on level 5 without tying off, about 30 minutes after the crew's morning huddle had covered the edge protection on that floor. He had received a written warning two years earlier for a similar breach on another project. The investigation, with Tom Kowalski present, found that his lanyard had been available, that the anchor point was installed, and that he had decided it was quicker to finish a short task without tying off.

Luis considered dismissal, because fall protection breaches are among the most serious on a site. He weighed the long service, the fact that the earlier warning was two years old, the immediate admission and apology, and the company's record of handling similar first and second breaches. He imposed a three-day suspension and a final written warning stating that any further fall protection breach would lead to dismissal. The union grieved the suspension at step 1, arguing for a one-day suspension, but withdrew the grievance at step 2 after reviewing the earlier warning and Calder Ridge's records of similar cases. The carpenter finished the project without further incident.

The case illustrates the balance arbitrators look for: a serious safety breach, real consequences, consideration of the mitigating factors, and consistency with how others had been treated.

Running a discipline meeting

The meeting where discipline is delivered is short, but it shapes how the worker and the crew see the decision. Luis coaches his foremen to hold it privately, never in front of the crew; to have the steward present where the agreement provides or the worker asks; to state the facts, the rule, the decision and the reasons plainly; to say what is expected from now on and what will happen if the problem continues; and to give the worker a chance to speak. The written record is handed over at the meeting or sent the same day. What supervisors should avoid is arguing about the decision, bringing up unrelated complaints, or making remarks about the worker's character. A worker who leaves the meeting understanding what went wrong and believing they were treated fairly is much more likely to improve, and much less likely to grieve.

The steward's role in the meeting is to represent the worker, ask questions and make sure the process is fair. Stewards sometimes argue strongly. A supervisor who stays calm, listens, and does not take it personally will usually find the steward easier to work with the next time.

Non-union workers

Calder Homes' non-union workers have no grievance procedure or arbitrator, but they are not without protection. Ontario's Employment Standards Act sets minimum rights, although construction employees are exempt from its notice of termination and severance pay provisions. Human rights law prohibits dismissal on protected grounds, and the OHSA prohibits reprisals against workers who raise safety concerns or refuse unsafe work. Outside the exemption, non-union employees dismissed without just cause can sue for reasonable notice at common law, and the courts set a high bar for dismissal for cause, looking at the misconduct in context. Good practice is therefore much the same as in the union setting: clear rules, investigation, progressive discipline and consistent records.
