David Chen arrived at MirrorTech at 8:47 AM on a Tuesday in October.

He always arrived between 8:45 and 8:50. Not earlier, because that would seem eager. Not later, because that would seem careless. Eight-forty-seven was the number he had arrived at through six years of careful observation and adjustment. It was the number that said: I am here, I am on time, I am not making a fuss.

The building was glass. All glass. A twenty-story tower on the Upper East Side that reflected the sky and the buildings around it and the people walking on the sidewalk below. David liked the building, in a way. It felt honest, or as honest as a building could be. Everything was visible. Everything was transparent.

He took the elevator to the 14th floor and walked to his desk. The office was open-plan, which was to say there were no walls between the desks, only low dividers that came up to about chest height. From his position, he could see the feet of the people sitting three desks away. He knew which ones had nice shoes and which ones didn't. He knew who was going through a divorce by the way their shoes were scuffed.

His desk faced a wall of glass that looked out over Central Park. On good days, he could see the trees changing colour. On bad days, he could see his own reflection superimposed on the trees, a ghost sitting in front of autumn.

"Morning, David," said Rachel Torres from the desk to his left.

"Morning."

"Did you see the new update to the efficiency dashboard?"

"Not yet."

"It's up. You should look at it."

"I will."

This was their typical morning conversation. Three sentences. Maybe four if Rachel asked about his weekend and he said something generic like "pretty quiet, just caught up on some reading."

David sat down and opened his computer. The first thing he saw was the efficiency dashboard, as Rachel had said. It was a large screen on the wall of the analytics team that showed real-time data about everyone in the building: who was at their desk, who was away from their desk, how many hours each person had spent in meetings versus at their desk versus in the bathroom.

David's number was 87%. That meant he was at his desk, working, for 87% of the time he was in the building. The team average was 82%. David was above average. This was good. Being above average was safe. Being below average was a conversation with HR.

He opened his email. Three messages: a reminder about the quarterly review, a link to a webinar on data visualization, and a message from Mr. Harrington, the CEO.

The message was short.

David—

Just wanted to say how much I appreciate your work on the Mirror system. You're one of the people who makes this company what it is. Keep up the excellent work.

Best, Greg

David read the message twice. Then he deleted it. Not because he didn't appreciate it, but because appreciating it felt like a trap. If he acknowledged it, if he replied with something warm and grateful, it would create an expectation. An expectation that he would keep up the excellent work. That he would always be above average. That he would never—

He closed the email and opened his work.

At 10:30, he went to the bathroom. The mirror above the sink showed him a man of thirty-four with thinning hair and tired eyes. He splashed water on his face and looked at himself for a moment. He didn't like what he saw, but he didn't dislike it either. It was just a face. A face he had been looking at for thirty-four years.

When he came back from the bathroom, Rachel was standing at his desk.

"David, can I talk to you for a second?"

"Sure."

"It's about my efficiency score."

"What about it?"

"It dropped to 71% yesterday. I don't understand how that's possible. I was at my desk all day. I was in three meetings. I answered every email."

David looked at the dashboard. Rachel's number was indeed 71%. It was the lowest on the team.

"The system tracks more than just desk time," David said. "It tracks response time, meeting duration, even how long you spend in the break room."

"So I spent too much time in the break room?"

"I don't know. I didn't write the algorithm."

Rachel was quiet for a moment. Then she said: "You see it, right? You see what's happening?"

"See what?"

"The system. The way it's used. It's not about efficiency, David. It's about control."

David looked at the dashboard. Rachel's number was red. His was green.

"I see it," he said.

"But you don't do anything about it."

"I—"

"Never mind." She walked away.

David sat at his desk and looked at his green number. 87%. Above average. Safe.

He thought about what Rachel had said: You don't do anything about it.

He was right. David didn't do anything. He had been thinking about doing something for two years. Maybe three. But thinking and doing were different things, and David was very good at thinking and very bad at doing.

At lunch, he ate at his desk. He always ate at his desk. The Mirror system tracked lunch breaks, and David's average lunch break was exactly twenty-two minutes, which was exactly the company average. He had calibrated it carefully over six months. Twenty minutes was too short and looked abnormal. Twenty-five minutes was too long and looked careless. Twenty-two was perfect.

He ate a sandwich and read the news on his phone. A story about a company in Silicon Valley that had been caught using employee surveillance software to monitor workers' bathroom breaks. The company had denied it. The employees had sued. The case was ongoing.

David finished his sandwich in twenty-two minutes.

At 2:15 PM, Rachel was called into a meeting with HR. David watched her go through the glass wall, her feet visible from his desk. She came back forty minutes later with a small box.

She didn't look at David as she walked past his desk. She just kept walking, carrying her box to the elevator.

David looked at the dashboard. Rachel's number was grey. Grey meant inactive.

That evening, David stayed late. He always stayed late, too. Not because he had a lot of work, but because leaving at the same time as everyone else sent a signal. If he left at 6:00 PM, when most people left, it would look like he was trying to blend in. If he left at 5:30, it would look like he was eager to go home. So he stayed until 7:15, when the building was mostly empty, and walked to the subway alone.

On the subway ride home, he thought about Rachel. He thought about her red number and her grey number and the box she had carried to the elevator. He thought about what she had said: You don't do anything about it.

He got home at 8:00. His apartment was small and quiet and clean. His wife Sarah was already home. She was a teacher at a public elementary school in Harlem, and she had been grading papers all evening.

"How was work?" she asked.

"Fine."

"Anything interesting?"

"No."

She nodded and went back to her papers. David made dinner—pasta with sauce, something simple—and they ate at the kitchen table without talking much. This was normal for them. They had been married for eight years, and the silence between them was not uncomfortable. It was just there, like furniture.

After dinner, David washed the dishes and Sarah graded papers. At 10:00, they went to bed.

"Did you tell them?" Sarah asked.

"No."

"Maybe you should."

"I don't know what I'd say."

"Tell them the truth. That the system is wrong. That it's dehumanizing. That it turns people into numbers."

David turned over in bed. "And then what? They fire me? They demote me? They give me a grey number too?"

"Maybe."

"Sarah, we have a mortgage. We're planning to have a baby."

"I know."

"Then maybe I shouldn't—"

"Maybe you shouldn't what? Survive?"

David didn't answer. He closed his eyes and listened to Sarah's breathing. She was asleep in two minutes. David took longer.

The next morning, he arrived at MirrorTech at 8:47.

He sat at his desk and looked at the dashboard. Rachel's number was grey. Next to her name, in small letters, it said: No longer employed.

David looked at his own number. 87%. Green. Above average. Safe.

He opened his email. No messages from Mr. Harrington. No messages from anyone. Just the usual: webinar reminders, company announcements, a birthday greeting for his mother.

He opened his work.

At 10:30, he went to the bathroom. The mirror above the sink showed him a man of thirty-four with thinning hair and tired eyes. He splashed water on his face and looked at himself for a moment.

Maybe tomorrow, he thought.

He went back to his desk and sat down.

The phone rang. It was his mother. She wanted to know if he and Sarah were coming for Sunday dinner.

"Yes," David said. "We'll be there."

"Great. I'll make your favourite. Meatloaf."

"Mom, you make meatloaf every Sunday."

"Then you'll have it twice this week. That's even better."

They hung up. David looked at the dashboard. His number was still 87%. Green. Above average.

He opened his work and started typing.

The days passed. October became November. The trees outside the glass wall turned from gold to brown to bare. David arrived at 8:47 every morning and left at 7:15 every evening. His efficiency number stayed at 87%. Sometimes it went to 88%. Once it went to 86%, and he spent the entire day trying to bring it back up, moving faster, answering emails sooner, spending exactly twenty-two minutes on lunch.

He saw other people's numbers change too. People who dropped below 75% were called into HR meetings. People who dropped below 65% left with boxes. People who stayed above 85% got promotions.

David stayed above 85%.

One afternoon in November, Mr. Harrington called a meeting of the entire analytics team. He was a tall man with grey hair and a warm smile, the kind of smile that made you feel seen and evaluated at the same time.

"I want to take a moment to recognize the amazing work this team has done this quarter," he said, standing at the front of the conference room. "The Mirror system has never been more effective. Our client base has grown 40% this quarter. Our efficiency scores are higher than ever. And that's because of people like David Chen."

He pointed at David. David looked up from his notebook.

"David has been a cornerstone of this team. Consistent. Reliable. Above average, every single day. That's the kind of employee who makes this company great."

The team clapped. David clapped too. He felt his face do something that might have been a smile.

After the meeting, a woman from his team—Heather, who sat two desks over—stopped at his desk.

"Congratulations, David. You deserve it."

"Thanks."

"I've been below 80% for three months. I don't know how much longer I can—"

"I'm sure it'll turn around."

"Maybe. Or maybe I'm just not cut out for this." She looked at the dashboard. "What's your number today?"

"87%."

"Of course it is." She smiled, but it wasn't a happy smile. "You're good at this, David. Better than I am."

"I'm not trying to be good at it. I'm just trying to—"

"To what? Survive? So am I."

She walked away. David looked at the dashboard. 87%. Green.

That evening, he stayed until 7:15 and walked to the subway alone. On the subway, he thought about Rachel and Heather and their red numbers and their grey numbers. He thought about Mr. Harrington's smile and the way it made you feel seen and evaluated at the same time.

He got home at 8:00. Sarah was grading papers.

"How was work?" she asked.

"Fine."

"Anything interesting?"

"No."

She nodded and went back to her papers. David made dinner. They ate. He washed the dishes. At 10:00, they went to bed.

"Did you tell them?" Sarah asked.

"No."

"Maybe you should."

"I don't know what I'd say."

"Tell them the truth."

"Sarah—"

"David, I'm not asking you to be a hero. I'm asking you to be honest. Just once. Tell them what you think. Tell them the system is wrong."

David turned over in bed. "And then what?"

"Then what happens. Whatever happens. But at least you'll have told the truth."

David closed his eyes. "Maybe tomorrow."

"Maybe."

He was asleep before she spoke again.

The next morning, he arrived at MirrorTech at 8:47.

He sat at his desk and looked at the dashboard. His number was 87%. Green. Above average. Safe.

He opened his email. No messages from Mr. Harrington. No messages from Rachel. No messages from anyone.

He opened his work and started typing.

At 10:30, he went to the bathroom. The mirror above the sink showed him a man of thirty-four with thinning hair and tired eyes. He splashed water on his face and looked at himself for a moment.

Maybe tomorrow, he thought.

He went back to his desk and sat down.

The phone rang. It was his mother. She wanted to know if they were still coming for Sunday dinner.

"Yes," David said. "We'll be there."

"Great. I'll make your favourite. Meatloaf."

"Mom, you make meatloaf every Sunday."

"Then you'll have it twice this week. That's even better."

They hung up. David looked at the dashboard. 87%. Green. Above average.

He opened his work and started typing.

And the mirror on the wall showed him a man sitting at a desk, typing, while his number stayed green and his life stayed the same and tomorrow stayed exactly one day away.
