Over the years, there were times when it was very windy out and when I walked into my workplace from the parking lot, my hair was very messed up, such that my hair was pointed in different directions or some of it was standing straight up. The people I worked with in the past told me whenever my hair was a mess and then I had quickly combed it to make it look neat again.
I am usually very good at remembering to pat my hair down right after coming inside my workplace on windy days and I will also look for a mirror to make sure that my hair looks good, if not, I take out my comb and comb it back into place. Yet, there have been times when I just completely forgot to check on my hair after entering the workplace.
I have begun to notice over the past year, that on very windy days, that none of my current coworkers will tell me if my hair is a mess when I come into the workplace in the morning or when we all return to the workplace after traveling somewhere for lunch.
I do not find out that it is a mess until I have to use the restroom and then I see in the mirror that it is a mess and then I feel like a complete fool for having walked around the workplace for X amount of time with messy hair. In contrast, I have often told my current coworker(s) whenever their hair is a mess so that they can quickly comb/brush it back into place and thus won't suffer any embarrassment. I want to point out that I am a man and that most of my coworkers are men.
This is making me wonder if some or all of my coworkers may actually want me to look bad because perhaps they may no longer like me and want me to look like a fool in front of our manager or in front of customers who come into our workplace, yet perhaps it may be that they think that I actually want to walk around with messy hair so they choose not to say anything to me about it.
If your coworkers do not tell you that your hair is messed up, could this be a sign that they do not like you?
EDIT
I just want to point out that I know that a coworker does not have any duty or responsibility to make you aware of an issue with your physical appearance, however if they truly like you and consider you a friend and not just a coworker, they will most likely tell you about it so you will not suffer any potential embarrassment within the workplace.
