A fixed weekly schedule doesn't necessarily make someone a day worker. In Lichter v. Treasury Board (Correctional Service of Canada), 2026 FPSLREB 94, the Federal Public Sector Labour Relations and Employment Board resolved competing interpretations of the correctional officers' collective agreement and awarded premiums to an employee working an accommodated evening schedule. The decision matters for employers and unions because the classification turned on what the agreement meant by regular work, not how often the employee's actual hours changed.
Rebecca Lichter worked at the Nova Institution for Women in Truro, Nova Scotia, at the CX 02 correctional officer level. Before a workplace injury, her duties involved a rotating schedule with 9 and 16 hour working periods. When she returned after medical leave, the employer and bargaining agent arranged a schedule within her functional limits. From January 23, 2017 until May 17, 2019 she worked 6 hours each day, from 15:00 to 21:00, Friday through Tuesday, with 2 days off. Her hours were predictable. They were also largely outside what most employees would understand as a normal daytime shift.
The employer treated Lichter as a day worker. She argued that she remained a shift worker entitled to premiums under article 25 of the collective agreement and to special holiday lieu hours. The parties agreed to a written hearing using an agreed statement of facts, documents and affidavits from workplace personnel. The dispute was not over what hours she worked. It was over the meaning of the agreement when it divided day work from shift work. See paragraphs 1 to 14.
When regular hours aren't day work
Clause 21.01 describes day work by reference to hours scheduled on a regular basis, while clause 21.02 covers a shift scheduled on a rotating or irregular basis. The word regular was not separately defined. It could mean consistent and predictable, which described Lichter's routine, or normal and standard, which did not describe an evening shift ending at 21:00.
This was an actual conflict in the Board's decisions. In Denboer v. Treasury Board (Correctional Service of Canada), 2016 PSLREB 58, the Board treated regular as meaning ordinary daytime work and regarded predictable evening hours as shift work. In Kay v. Treasury Board (Correctional Service of Canada), 2025 FPSLREB 16, the Board expressly rejected that approach, reasoning that a stable schedule satisfied the day work provision even when the employee's working hours were overnight. The present adjudicator did not resolve that conflict by pretending the cases involved fundamentally different facts. He found they had adopted different meanings for the same contractual language and undertook the interpretation afresh. See paragraphs 15 to 27.
The parties offered evidence about practices at other institutions, scheduling systems and labour relations bulletins. Christopher Rootham considered that material but found it inconclusive. A manager's evidence suggested that 5 equal working days were consistent with day work, which didn't establish that they were necessarily day work. The other employee's evidence about typical daytime schedules similarly failed to settle the contractual meaning. A manual alteration to a payroll record wasn't an admission that the employer had interpreted the agreement incorrectly. See paragraphs 28 to 38 and 48.
Instead, 2 features of the text decided the issue. The heading above clause 21.01 was day work, which indicated work during the hours normally associated with daytime rather than any part of a 24 hour period. A shift ending at 21:00 fell well beyond that understanding. And clause 21.02 used rotating or irregular as alternatives. If irregular only meant changing or inconsistent, the word rotating would do no separate work. Reading the provision so that both terms mattered supported treating irregular as work outside standard daytime hours, even when those hours happened reliably each week. That reading was also consistent with the ordinary principle that an agreement's words should be considered in context without making part of the wording redundant. See paragraphs 39 to 50.
This reasoning rejected the idea that shift work necessarily involved a particular number of hours in each work period. Another clause contemplated an 8.5 hour working day, but the negotiated correctional schedules themselves included other lengths. Those details didn't override the definition. For the hours and agreement at issue, Lichter was a shift worker between January 23, 2017 and May 17, 2019.
The separate accommodation and estoppel arguments
Lichter argued in the alternative that the employer couldn't change her previous shift classification because she had relied on it. The Board rejected that estoppel theory. Earlier premiums had been paid while she was on an actual rotating schedule before the fixed return plan took effect. That wasn't a clear representation that premiums would continue on any later schedule. There was also no evidence she had arranged her affairs differently in reliance on such a promise, or suffered detriment through that reliance. See paragraphs 51 to 54.
She also argued that withholding premiums and holiday lieu hours amounted to disability discrimination. The Board did not accept an entitlement to compensatory premiums merely because an employee had been accommodated. Compensatory benefits depend on the work actually performed. An accommodated employee assigned to a genuinely nonshift position would not automatically receive shift premiums for hours not worked as shifts. Lichter's success came from the Board's separate conclusion that she had in fact worked qualifying shift hours under the agreement. This matters because the decision isn't a blanket ruling that every accommodation arrangement preserves every previous pay element. See paragraph 55.
Premiums awarded, but not double holiday benefits
The Board declared Lichter a shift worker for the disputed period. Clause 25.01 provided a premium of $2 for each hour worked between 15:00 and 07:00. Clause 25.02 also provided a weekend premium for employees on shifts who worked weekends. Because her Friday to Tuesday schedule included weekend work, the Board ordered both categories paid for the qualifying hours. The employer had 75 days from the July 20, 2026 order to calculate and pay what was owed. The Board retained jurisdiction for 90 days to resolve any dispute about the amount. See paragraphs 56 to 59 and 65 to 68.
Her claim for statutory holiday lieu hours was different. Shift workers ordinarily accrued such hours in place of designated paid holidays. The evidence showed that Lichter had already received paid days off for those holidays while classified as a day worker and had not been required to work on them. Giving her both the paid holidays and additional lieu hours would have compensated her twice for the same benefit. The Board refused that part of the claim. See paragraphs 60 to 63.
The order therefore involved 3 separate conclusions. Lichter was a shift worker on the proper reading of this agreement, so the employer owed shift and weekend premiums. The accommodation arrangement wasn't by itself a promise to maintain all former benefits or proof of disability discrimination. And correcting a misclassification did not entitle her to receive holiday compensation twice.
What the ruling means in practice
In a correctional workplace, payroll classification should be checked against the actual negotiated language before assuming that a permanent schedule, a shorter accommodated shift or the absence of rotation makes an employee a day worker. The description of the schedule and its surrounding headings can be as important as how frequently the hours change. Where a collective agreement contains competing possible meanings, prior cases may illuminate the disagreement without settling it, especially if those cases themselves conflict.
The holding is specific to this correctional collective agreement and the schedule ending at 21:00. It does not rewrite every shift premium clause in Canadian collective agreements, impose a universal definition of daytime or decide the separate legal standard for providing disability accommodation. Relief also remains subject to the employee's actual entitlements and the rule against paying the same holiday benefit twice.

The employment law significance
The case illustrates why an employer implementing an accommodation plan has to consider pay obligations under the actual agreement rather than assume that changing the employee's hours necessarily changes every negotiated classification. The Board separated those contractual entitlements from Lichter's unsupported estoppel claim and her argument about disability discrimination. Maintaining an accommodation doesn't erase contractual compensation for work actually done, and awarding that compensation doesn't justify duplication of holidays that have already been paid.
