On Aug. 1, 2018 (maybe) the federal government’s plan to legalize
recreational marijuana will come into effect and no doubt, employers
will be faced with questions about how to manage weed in the workplace.
Do not expect the law to provide employees with carte blanche to get
high at work. A recent decision by a labour arbitrator provides a good
reason to believe that discipline up to the point of discharge will
remain the reasonable response to employees’ drug use.
In University of Windsor and CUPE Local 1001, two janitorial
staff were terminated following an investigation into allegations that
they had smoked marijuana during their shift. The employees were sitting
in one of their cars while on break during a shift at the university.
They were approached by campus police and the officer noticed a strong
smell of freshly-smoked marijuana. The officer asked the employees if
they had smoked marijuana, and if they had any marijuana on them. They
initially denied, but once informed that the police would have to be
involved, they relented that they had smoked up and handed over a
baggie. The employees denied however that they smoked on campus.
The employer investigated and determined that the employees were not
being honest, and in fact that they had been smoking marijuana on campus
during their shift. The university decided to terminate the employees
for just cause, relying on their possession and consumption of an
illegal substance on campus, the safety sensitive nature of their
position, their access to locked areas of the campus, their proximity to
students, the fact that they were not honest about their conduct, and
ultimately the employer’s loss of trust in the employees. The last
factor was crucial given that the janitorial staff work largely
For its part, the union argued that the university should have abided
by the principle of progressive discipline. The employees each had 17
years of service with the employer, and had no notable disciplinary
history. Further, while the janitors worked without supervision, their
jobs could hardly be considered safety-sensitive. The union argued for a
more lenient penalty than termination.
The arbitrator stressed that each case involving drug use at work
must be determined on its own specific facts, context, and merits. In
his own words, the arbitrator stated "There is no simple formula that
can be applied in determining the appropriate penalty in cases of
illicit drug use at work.” He agreed with the union that the employees
were not in a safety sensitive position, but ultimately he agreed with
the employer that the employees’ lack of candour and their attempts to
mislead the employer destroyed the trust necessary for them to continue
working in an unsupervised position. Accordingly, the terminations were
How will legalization of marijuana affect employment law?
There is no simple answer to that question.
The most significant element of this arbitrator’s decision is that
termination for being impaired at work is not automatic, and each case
has to be assessed on its own circumstances. If these employees had been
contrite and honest about their conduct from the outset, it seems as if
the arbitrator would have reinstated them. On the other hand, if they
did work in a truly safety sensitive position, perhaps even perfect
candour would not have saved them.
The fact that marijuana has historically been illegal for
recreational consumption is just part of the equation. Employers can and
should, even after Aug. 1, implement workplace policies prohibiting
employees from being or becoming impaired at work, particularly in
safety sensitive positions.
I can imagine that some ill-considered employees might cockily tell
their managers that they are untouchable once recreational pot is legal.
That is nonsense. Alcohol is legal, but any employee who gets drunk at
work is bound to be disciplined or fired (pending the inevitable
‘disability’ defence). The same outcome will always be possible for any
employee who is impaired at work by any other drug, even if legal.
In fact, medical marijuana has been a reality in Canadian workplaces
for some time now, and it has been dealt with like any other medication.
Certain criteria need to be in place for an employee to be able to use
marijuana as a medicine and still attend for work; such as a proper
prescription and safeguards for any potential workplace hazards. The
same holds true with regard to prescribed opioid painkillers, for
example. Even though they are not being taken for recreational use, an
employee impaired by prescription medication may not be allowed to work,
and if they recklessly attend for work in a safety sensitive position,
discipline could result in the right circumstances.
There is no doubt that employers will need to adjust to a new
pot-friendly society, but new laws surrounding what adults can consume
in their personal time will not automatically re-write decades of legal
precedents concerning workplace impairment.
