June 12, 2022 - Reading time: 12 minutes

One of the most common types of affair is a workplace affair, where a person gets too close to someone that they work with. If you think that your partner is having an affair at work, it can be stressful as you try and uncover the truth. The small comfort is that this is not an uncommon feeling, with many people are the world questioning their partners’ behaviour and intentions as they believe that they have been unfaithful.

Workplace affairs can be difficult to identify as you may not see how your partner interacts within the workplace. As professional, experienced private investigators, this is where we come in. We can help uncover if your partner is being unfaithful, allowing you to know the truth and find some peace. 

There are many warning signs that your partner may be having an affair with someone that they work with, and it is important that you are aware of these warning signs to keep track of any changes in their behaviour. 

To help you out, we have utilised our years of experience in the private investigation field to provide you with a quick guide that includes five signs that your partner may be being unfaithful at work. These signs can help you strengthen your suspicions before investing in private investigation services to uncover the truth. Let’s take a closer look:

What Are The Tell Tale Signs That Your Partner Is Having an Affair at Work?

If you suspect that your partner is cheating on you with someone they work with, it can be difficult to prove or find out more information unless you work in the same place! As private investigators, we are able to conduct investigations subtly in order to find the answers that you can’t access.

To give you some kind of idea, however, we have put together a list of five key signs that we often see in cheating partners that get involved with a co-worker. Use this list as a starting point to help find out the truth. Take a look at our red flags below and see how they compare to your own situation:

1. Their Working Schedule Changes Unexpectedly

If your partner has a regular job which starts and finishes at the same time every day, or routine shift work, it is normal to be able to predict their working habits. If these habits change, it may be a sign that they are spending more time at work to be around a certain person. 

Look for instances when they need to work late when this is not their norm, or if they have to go in on days they don’t usually have to. A one-off could be a unique work circumstance, but a pattern of events like these can indicate that they are trying to hide something.

When they are telling you about working late, look at how they are delivering this information- are they casual and making eye contact, or do they refuse to look at you and quickly mention it before moving on to another topic of conversation? The delivery of this news can be a key indicator. 

2. Their Appearance Changes Unexpectedly and They Start Putting More Effort In

As a person enters a new relationship and is trying to impress someone new, they want to look their best. Therefore, you might begin noticing a change in their appearance and that they are making more effort than they usually would.

Are they wearing clothes they would normally keep for social occasions? Are they more groomed than usual or are putting on more make-up or aftershave? These can be signs that they are seeking attention from someone else. 

3. Work Events Become Far More Common

As the affair progresses, your partner may be looking for a reason or excuse that they can give to justify spending more time away from home so that they can continue their affair. Often, work events are used as the perfect excuse as they expect their partner not to question them. If your partner never attended events such as business trips, large conferences or parties before, and they begin to all of a sudden, this may be a sign that there is another motive behind their behaviour. 

If they do go on business trips regularly normally, it can be harder to tell. Think about if the length or frequency of these trips has changed, or if they are now cancelling plans with you or their family to attend them. This would be out of their normal routine and could be a potential red flag. 

4. They Are Constantly Attached To Their Phone

One of the most obvious tell tale signs that a person is having any kind of affair is that they are constantly attached to their phone. Now, it is important to note that we do rely on our phones a lot nowadays, but had your partner's mobile phone usage increased? Are they becoming more secretive and hiding what they are doing? You may find that they are hiding their phone when they are not using it so that you cannot see it, or they are deleting messages to others so you can’t look back on what they are talking about.

If you do notice that they are on their phone all the time, who are they contacting? If it is a work colleague of the opposite sex, you may start to question why they are so close all of a sudden and if they are having an affair. 

5. They Do Not Respond Well To Questioning And Become Defensive 

If a person is having an affair at work, they will be working hard to hide it and cover their tracks, but this can be stressful. Therefore, you may find that when you ask them simple questions about their work day or reasons why they have had to work a weekend or stay late, they may quickly become cagey and defensive in the way that they answer. 

Often, they might shut down the conversation or try and change the topic to take your mind off their questioning, or they may give vague answers that lack any real detail or information in the hopes that you will then move on. 

Another way of dealing with this type of questioning is to immediately react like they are being attacked, and reply in a blunt or angry manner, making you feel like you have done something wrong. This is a strong sign that they may be hiding something as if they had nothing to hide, they won’t have had such a strong reaction to basic questions. 

What Should I Do If I Have My Suspicions That My Partner Is Having An Affair?

Often, if an individual has a bad feeling in their gut and a suspicion that something is wrong, it is because there is. If your partner is displaying some of our tell tale signs or is hiding information from you, it is important to talk to someone about it to help process your feelings.

On top of this, we recommend that you contact a trusted private investigator who can work hard to either confirm or deny your suspicions, rather than leaving you with no real answer. Private investigators have a particular set of skills that allow them to uncover information that you may not be able to access yourself. This skill set can include undercover surveillance, investigation into online presence and mobile phone usage. They understand the law on surveillance and ensure that they use legal methods to find out the answers to your questions.

How Common Are Workplace Affairs In Real Life?

The story goes that we often spend more hours with those who we work closely with than who we are in relationships with, and you know what, depending on the job that you do, this might be true. 

We often get ideas or suspicions about workplace affairs as we often see them dramatised on film and tv – with workers gradually becoming closer before they cross the line. But how common are they in real life? Well, we’ve looked into the research and unfortunately, they are more common than you may think. When asked in a survey, around 20% of people admitted openly to having an affair at work, but it is important to note that the true number may be much larger. This is because many may have participated in an affair with their co-worker, but may not want to admit it because they are scared of getting found out, or they are ashamed of their behaviour and do not want the judgement that comes with the confession. When another survey asked people to admit if they knew someone who had been unfaithful with someone from their workplace the number sat at just under 50%.

How Do Workplace Affairs Develop?

As mentioned above, workplace affairs often develop when two people are spending a lot of time together – long hours working on a project where collaboration is key. While close working relationships with colleagues aren’t necessarily a bad thing, sometimes feelings can get involved and a person can cross a line.  Workplace affairs rarely happen quickly and instead can take weeks or even months to develop. The initial move from a friendship to an affair can happen in the workplace setting or while the two involved are socialising at a work event or business trip. As the majority of the affair occurs during working hours, it can be difficult for a partner at home to detect, especially if they do not know what their partner’s co-workers are like. 

When it comes to workplace affairs, there are different types of affairs. Some affairs between co-workers are simply about sex and intimacy and are very physical. These types of affair tend to have fewer emotions and feelings involved. On the other end of the spectrum are affairs where feelings occur, emotions are strong and there is a real possibility of a long-term connection. No matter which, type of affair, however, the hurt that an innocent partner can feel can be extremely damaging. Therefore, if your partner is having an affair, it is important to try and identify the situation early to limit the damage and be able to move on.
