Having healthy and strong relationships at work does also have downsides. A study with over 1000 participants found, that relationships at work can also affect the work-life-balance or inhibit colleagues to give critical feedback, because they don‘t want to hurt the other persons feelings.
You are more likely to share private information which makes it harder to maintain privacy in areas of your life you don‘t want to share with your colleagues. And lastly while relationships can improve your productivity they can also distract you from working because you are tend to be distracted by conversations of your co-workers.
