Workplace anxiety: when work stress starts to take over

When Work Stress Turns Into Anxiety

Work stress is something most of us deal with. For some people, it grows into something more: workplace anxiety that follows you home and doesn’t let go, even after you log off.

Workplace anxiety can show up in different ways. Common signs include:

Checking email over and over, even outside work hours
Rehearsing conversations before they happen, then replaying them afterward
A constant worry that others will find you out, even when your reviews say you’re doing well
Physical tension, like a tight jaw, shallow breathing, or a knot in your stomach before a meeting
Trouble fully disconnecting on evenings, weekends, or vacation

Workplace anxiety is a common response to ongoing pressure at work. Support can help.

Work stress is so common that most of us stop questioning it. Deadlines, meetings, and a full inbox can start to feel like part of the job. Workplace anxiety is different. It’s what happens when that stress stops staying at work and follows you home, into your evenings, your weekends, and the mornings before you’ve even logged in.

You might dread opening your inbox before you’re at your desk. You might replay a meeting for hours, certain you said the wrong thing or missed something important. Your shoulders may stay tense long after you’ve logged off, or Sunday evenings might bring a tight, uneasy feeling before the week has even started. You might reread a manager’s message three or four times before deciding whether anything is actually wrong, or skip lunch some days, telling yourself you’ll eat later even when your workload doesn’t actually require it. The people closest to you might notice you’re short-tempered over something that used to roll off you, like a grocery order arriving late or a change in weekend plans.

How workplace anxiety shows up day to day

Workplace anxiety usually looks like a slow shift: someone who looks capable on the outside is dealing with a lot no one else can see. Common signs include:

Checking email over and over, even outside work hours, because you’re afraid of missing something

Rehearsing conversations before they happen, then replaying them afterward

A constant worry that others will find you out, even when your reviews say you’re doing well

Difficulty making decisions, or spending a lot of time on small decisions because you’re afraid of getting them wrong

Physical tension, like a tight jaw, shallow breathing, or a knot in your stomach before a meeting

Trouble fully disconnecting on evenings, weekends, or vacation

If you live with workplace anxiety, there’s a good chance you’re also a high performer, and that’s often true for good reason. Anxiety and competence often exist together, which is part of why this pattern can go unnoticed for years. The work still gets done. It just costs your mind and body more than it should. This pattern shows up often in men who feel pressure to be the provider, which we cover in more depth in our piece on men’s mental health in the GTA. Anxiety shows up differently for everyone, though, regardless of your role or background.

What can drive workplace anxiety

A few patterns come up again and again in our work with clients:

Unclear expectations: when you don’t know what “good” looks like, or the rules keep changing, it’s easy for your mind to jump to the worst case. You might get positive feedback one week and vague criticism the next, for the same work, with no explanation of what changed.

A heavy workload with no breaks: long hours with no time to recover can keep your body tense and make anxiety more likely. Skipping lunch, answering messages after hours, or working through weekends might feel necessary, but your body still needs time off to settle.

Difficult relationships with managers: inconsistent feedback, favouritism, or a manager who leads through fear can make the environment itself a source of anxiety, on top of the work. You might catch yourself rehearsing how to phrase a simple update so it can’t be misread, or feeling on edge before a routine check-in.

Job insecurity: restructuring, layoffs in your field, or a probationary period can keep you on edge even when you’re doing your best work. A passing comment about budget cuts can set off days of worry. If you’re also newer to Canada, unfamiliar workplace norms and precarious status can make this feel even more intense. Our guide on anxiety in newcomers to Canada goes deeper into that side of it.

Commuting and logistics: if you’re driving across Mississauga, Brampton, or the Peel Region every day, traffic and delays can add another layer of stress on top of an already hard day. That extra hour or two behind the wheel, or squeezed onto a packed GO train, is time your body doesn’t get to properly wind down.

Return-to-office and hybrid changes: shifting back to in-person work after years of a different routine has added a new source of stress for many people. Routines you built around remote or hybrid work, like exercising at midday or picking up your kids from school, can feel like one more thing slipping away.

Why work feels different now

Part of what makes workplace anxiety today different from a generation ago is how the job itself is structured. A typical workday now involves constant switching between email, chat apps like Slack or Teams, and project boards. In a 2009 study published in Organizational Behavior and Human Decision Processes, psychologist Sophie Leroy found that when you move to a new task before finishing the one before it, part of your attention stays behind, still processing what you left. This happens even more when the task you left was urgent or upsetting, like a tense email or a message from your manager.

A normal workday can involve dozens of these small, unfinished switches, and each one leaves something behind. The result can feel a lot like anxiety: a scattered, foggy feeling by mid-afternoon, trouble settling into deep focus, or a constant physical tension you can’t quite trace to one cause.

Why speaking up at work isn’t always simple

A lot of workplace mental health advice starts and ends with “talk to your manager.” In practice, that’s not always straightforward. According to CAMH (the Centre for Addiction and Mental Health), roughly three-quarters of working Canadians say they’d be reluctant to talk to a boss or coworkers about a mental health issue, mainly out of fear of being judged or facing consequences at work. That hesitation is common, and it’s worth taking seriously.

Psychological safety, a term coined by Harvard researcher Amy Edmondson, means feeling safe enough to speak up about mistakes, concerns, or struggles, and to be honest when things are hard. Some workplaces have it. Many don’t yet, and building it is mainly the employer’s job. In Ontario, employers with 25 or more staff are required to have a written policy on disconnecting from work outside business hours. It puts some of that responsibility on your employer.

Many Canadian employers also offer Employee Assistance Programs (EAPs) or accommodations for staff managing a mental health condition. These can genuinely help, but they work best where psychological safety already exists. If you’re not sure whether your workplace has that kind of safety, that’s worth exploring with a therapist before you decide how much to share at work.

How common this is in Canada

If you’ve been wondering whether what you’re feeling matters, the numbers say yes. Every week, an estimated 500,000 Canadians miss work because of a mental health problem, according to the Mental Health Commission of Canada. Mental health-related leaves also cost employers about double what a physical health leave does, according to CAMH. Workplace anxiety is one of the most common reasons Canadians can’t show up to work the way they want to.

What it costs outside of work

Workplace anxiety doesn’t stay contained to nine to five. It follows you home, and the cost isn’t only measured in sick days or missed deadlines. Partners and kids might notice you’re distracted or short-tempered even when nothing has actually gone wrong. Friends might hear “I can’t tonight, I’m too drained” one too many times before they stop asking. Exercise, hobbies, and the things that used to help you feel like yourself are often the first to go, because work is already filling your head. This cost never shows up on a pay stub or a performance review, and over time it can wear on the relationships that matter most to you.

Burnout, imposter feelings, and showing up while struggling

Workplace anxiety can feed burnout, and burnout can feed anxiety. Anxiety keeps your body on edge, even during evenings and weekends when you need rest, and if you don’t get enough time to recover, you run out of energy. You may start to feel more detached or cynical about your work. Things that used to be simple, like replying to an email or planning your day, start taking more effort, which can add to the worry about falling behind.

Another common pattern is imposter feelings: the sense that your success is mostly luck that could run out at any time. You might over-prepare for routine tasks, avoid asking questions because you’re afraid of looking unprepared, or downplay your role even when a project clearly succeeded because of your work. These feelings can happen even when you’re genuinely doing good work. Promotions, positive reviews, and finished projects often don’t settle the worry for long, because the evidence was never what created the worry in the first place.

Workplace anxiety often shows up as presenteeism: being at work, in the meetings and on email, but running far below your capacity because so much energy is going toward managing how you feel. You can be meeting every deadline and still be stretched thinner than anyone around you realizes.

What can help

Marking a clear end to your workday can help, maybe by turning off notifications outside set hours, or building in a small transition between work and home.

It can help to name what’s actually setting off the anxiety. Vague, constant worry is hard to work with, and a therapist can help you sort out whether it’s about a person, a task, or a deeper fear. If you’re not ready for that yet, our guide to mindfulness practices is a place to start on your own.

Keeping space for the things that help you recover matters too. A lunchtime walk, a workout, or a hobby can feel optional when work gets busy, but when they go, anxiety has more room to take over everything else.

Talking to someone you trust outside of work can help. A partner, friend, or family member can’t fix a difficult workplace, but saying it out loud can help you make sense of it, and remind you it doesn’t have to follow you everywhere.

How Cornerstone can support you

You may find cognitive behavioural therapy (CBT) especially useful for workplace anxiety. It targets the cycle of repeated worry and worst-case thinking that so often comes with it, and helps you build steadier thought patterns.

Our Clinical Director, Father Pishoy Wasfy, holds a Doctor of Counselling and Psychotherapy with a specialization in supervision and self-care. He’s written about self-care as a collective responsibility in counsellor training programs. His argument: self-care has to be built into how a program or supervisor operates. The same principle applies well beyond clinical training. Recovery from workplace anxiety usually needs more than one more productivity tip.

At Cornerstone, we work with many people carrying heavy workloads, including teachers, healthcare workers, and professionals across the Peel Region. Every therapist has a master’s degree and is registered with the College of Registered Psychotherapists of Ontario (CRPO), under doctoral-level clinical supervision. We offer evening and online sessions to help counselling fit around your workday. If you need support soon, our Rapid Access Counselling option can connect you with a therapist quickly.

If dread has become part of how you feel about work most days, that’s worth paying attention to.
