• Patrick Synge fired one of his employees for secretly working a second remote job while on the clock.

• He shared how he caught the employee and why he decided to fire them.

• He says overemployment is sometimes "unethical" and can hurt worker productivity.

This as-told-to essay is based on an email conversation with Patrick Synge, the cofounder and chief commercial officer of the business-process-outsourcing and remote-recruitment company Metrickal. The business is headquartered in Barcelona and has 10 full time, fully remote employees, in addition to more than 200 contractors worldwide. The following has been edited for length and clarity.

I'm the cofounder and CCO of a business where every employee works fully remotely. In January, I caught one of them secretly working a second full-time remote job.

Here's how it all played out — and why I decided to fire them.

My business is headquartered in Barcelona, but one of my employees was based in Peru. He was hired in 2022, and in the beginning, he did his job very well. But then, I started to receive complaints from clients about missed assignments and deadlines. He had also become quite unresponsive. These complaints from clients started to become somewhat regular.

When this employee started refusing certain shifts he usually worked, I became suspicious. I had a feeling that he was doing something on the side, but because there was no proof, I didn't want to jump to any conclusions.

So instead, I had one-on-one meetings with him to discuss his job performance. When the same issues continued, I told him that if things didn't change, I'd have to let him go.

While he showed some signs of improvement, his overall performance didn't change much. This put a significant burden on the rest of the team, who had to cover his shifts and deal with missed deadlines.

How I ultimately caught him

In December, unrelated to this particular employee, my company rolled out the time-tracking software called DeskTime.

My long-term goal is to introduce a four-day workweek at my company, and I decided the first step in this process would be understanding how my employees spend their time and what could be optimized to boost productivity.

So our entire team of full-time employees and freelance contractors started using DeskTime. They each had to install the app on their computers, so everyone was well aware that this was being implemented.

After a few weeks, I looked through the tracking data of the struggling employee and noticed there was another company's name — a US business — that regularly appeared in the data. It became clear to me that this employee had worked on some other company's tasks.
