Dealing with a Co-Worker Who Undermines You: Should I Refuse to Train Him?

Should she train her coworker who undermines her, or protect her work? The tension is rising, and the decision isn't easy.

A 28-year-old woman refused to train her new coworker after he spent two months interrupting her, bulldozing her ideas in meetings, and somehow ending up with clients praising him for work she clearly started.

On a small marketing team, OP has been paired up with Tom, a 30-year-old who keeps taking over discussions while she’s presenting, then dismisses her when she confronts him. Her team lead knows something’s off but has not stepped in, and the tension is getting so bad that even her boss is now forcing her to train Tom on a software she mastered before he joined.

The real problem is simple, if she teaches him the tool, will he finally learn how to steal her momentum even faster?

Original Post

I'm (28F) currently working in a small marketing team where I've been assigned to work closely with a new colleague, let's call him Tom (30M). Ever since Tom joined the team about two months ago, things have been a bit rocky.

Not only does Tom constantly interrupt me during meetings, but he also tends to take over discussions when I'm presenting my ideas, making it seem like he came up with them.

For background, I've brought this up with our team lead, who acknowledges the issue but hasn't taken any concrete action yet. I’ve tried addressing Tom directly, but he dismisses my concerns and claims he's just trying to improve our projects.

The tension at work is becoming unbearable, especially when clients have started praising Tom for ideas that originated from me. Recently, our boss assigned me the task of training Tom on a new software that I mastered before he joined.

It's a crucial tool for our projects, and I know that learning it would greatly benefit him. However, I can't shake off the feeling that once he learns it, he'll once again try to overshadow me and take credit for my work under the guise of 'collaboration.' So, here’s the dilemma: would I be the a*****e if I refused to train Tom on the software, knowing that it might hinder his progress but also protect my own contributions from being stolen?

The Dilemma of Trust

The original poster's struggle with Tom highlights a thorny issue many face in the workplace: trust. After just two months, Tom's undermining behavior not only chips away at her confidence but also complicates the team dynamic. The OP's hesitation to train him stems from a deep-seated fear that doing so might give him the tools to further diminish her contributions. It’s a classic case of self-preservation versus collaboration, and it raises a crucial question: can you truly work together when trust is fractured?

This situation resonates because it reflects the reality of many professional environments, where competitive spirits can overshadow teamwork. The OP's predicament illustrates how quickly a seemingly simple task, like training a coworker, can spiral into a moral dilemma.

OP is already dealing with Tom interrupting her and taking credit in meetings, so the training assignment feels less like help and more like a setup.

YTA if you don't train him. Being a team player is important, and by withholding training, you're stooping to his level. Teach him, but document every contribution you make for future reference.

NTA. Protect your work. If your boss isn't taking action, it's valid to have reservations.

After clients start praising Tom for “his” ideas that came from OP, the team lead’s vague acknowledgment starts to feel useless.

ESH. Tom for undermining you, and you for considering holding back knowledge. Training him could be an opportunity to set firm boundaries and establish your expertise.

It also reminds me of the slack coworker situation, where someone wondered if they could refuse covering Tom’s share of office duties.

TBH, I'd be wary too. If he crosses the line even after training, escalate the issue to your boss again.

Then her boss drops the new software training on her, and OP worries that one click-through tutorial could turn into another round of credit-snatching.

Wow, what a tough spot to be in. Your concerns are valid, so NTA for feeling this way. I'd say train him, but keep a record of your contributions moving forward to protect your work.

Now OP has to decide whether she refuses to train Tom and risks his progress, or trains him and risks her work getting rebranded as collaboration.

Community Divided

The Reddit community's reactions to the OP's plight reveal how polarized opinions can be when it comes to workplace ethics. Some users empathize with her reluctance to train Tom, arguing that he clearly doesn't have her best interests at heart. Others advocate for a more collaborative approach, suggesting that training him could ultimately benefit her credibility and career growth.

This division underscores the complexities of workplace relationships. It’s not just about individual actions; it's also about the power dynamics at play. Tom's behavior can be seen as a reflection of insecurity or ambition gone wrong, making it difficult for the OP to navigate her response without feeling like she’s compromising her integrity.

The Bottom Line

This story captures the essence of workplace conflict, where personal and professional boundaries blur.

The original poster's struggle with Tom reveals just how quickly workplace dynamics can shift from collaboration to competition. Tom's persistent undermining—interrupting meetings and claiming credit for ideas—creates a toxic environment, prompting the OP's understandable hesitation to train him on crucial software. This dilemma reflects a broader issue of trust; without it, even simple tasks become fraught with anxiety about self-preservation versus teamwork. The polarized reactions from the Reddit community further highlight the challenges individuals face in navigating these complex relationships while trying to maintain their professional integrity.

If Tom already steals the spotlight, teaching him the software might be the exact moment OP’s credit vanishes for good.
