Krisof,

The Buddha teaches that we exists in others and others in us. Even if you are secular, it cannot be denied that inside we are all the same; that we share similar worries, convey similar joys, feel similar stresses, express similar satisfactions, suffer similar anxieties, among other things. When you come to recognize that we are all the same, your anxieties of feeling judged will disappear. However, this does require practice. Whenever an interaction or event with a coworker passes, take time to repeat a mantra such as this:

This/these coworker(s) of mine
share(s) all my joys and sufferings
may my brother(s)/sister(s)
find peace, bliss and harmony

While this may be a poor example, you can definitely come up with one of your own. A mantra, or saying/quote, that expresses common relation will help promote your sense of togetherness with your coworkers and all other human beings. This should help you remove and diminish your feelings of being judged.

I hope this helps.
