When faced with interpersonal issues at work, it is important to first assess the situation and explore potential solutions before considering resignation. In your case, it seems that you have been experiencing a deterioration in your relationship with your colleagues since you were assigned to work in the subsidiary company. This change in attitude and the resulting impact on your work performance is causing you anxiety. Before making a decision, I would recommend taking the following steps:1. Communicate: Reach out to your colleagues individually to understand their perspective and address any misunderstandings. Clear and open communication can help bridge the gap and rebuild working relationships. 2. Seek support: Talk to your immediate supervisor or HR representative about the issue, expressing your concerns and seeking guidance on how to improve the situation. They may be able to mediate or provide advice on conflict resolution.3. Reflect on performance: Analyze the mistakes that led to your colleagues' resentment and try to learn from them. Show your commitment to personal growth and improvement, which might help regain their trust.4. Seek common ground: Look for shared goals or interests that can help reestablish a positive connection with your colleagues. Engaging in team-building activities or volunteering for collaborative projects may help rebuild relationships.5. Evaluate job satisfaction: Assess whether the overall work environment, including other factors beyond the interpersonal conflict, still aligns with your long-term career goals and values. Consider if the company culture and job responsibilities are fulfilling for you.Ultimately, the decision to leave the company should be a last resort after exhausting all possible solutions. Leaving prematurely may hinder your professional growth and can have an impact on your resume. However, if you have tried all available options and the situation remains untenable, it may be worth considering seeking opportunities elsewhere where you can thrive and work in a supportive environment. Remember to make a well-informed decision that considers both your short-term and long-term career prospects.
