Dear friend,
You have written your post with slight confusion. Who exactly passed disparaging comments against you? Was it HR Manager or someone else? Are you referring your HR Manager as "boss"? Anyway, I interpret the remark of your boss in the following way:
a) Your boss could be uncouth in general. Therefore, while telling you to leave the office, he told in very unprofessional manner. How is his conduct with others? Did you hear similar comment while talking others as well?
b) If the general conduct of boss is ok with others but he passed unsavoury remark only against you then it shows somehow he is frustrated against you. How is your relationship with him? Is it strained?
Whatever reason may be, boss must maintain professional conduct at the workplace. In fact, if some other employee behaves unprofessionally or casts a disparaging remark, then seniors should step in. Unfortunately, it is other way round.
I recommend you sending a mail to the boss asking for personal meeting. In the personal meeting give him feedback. Make sure that there is no one else in the room. Lodge your protest on his remarks but be polite. In case if he wavers, tell him that this meeting is only for this remark and nothing else. Do not talk on any other subject. Record the conversation between both of you but do this surreptitiously. Once you reach home, take the back up of this audio file.
For Kamesh: - The remarks are in Marathi. Direct translation would be "Hey bull, quit the office". But if translated loosely, it could mean "Hey idiot, leave the office now".
For Mr Nathrao: - Indirectly you have advised to wait and if he repeats such remarks then give him feedback. However, if such tendencies are nipped in bud, the better. If the originator of the posts downplays the comments, then it could embolden the boss further. In case, if the boss is MD of the company, then then there is a risk of boss taking the feedback personally. However, some time we have to take the bull by the horns.
General comments: - As of now we do not know whether boss is HR Manager or someone else. Nevertheless, it was wrong on the part of that person to refer the originator of this post in offensive manner. In many companies, a systematic training is conducted on workplace etiquettes or corporate behaviour. Far from it, here we have either HR or someone from leadership passing contemptuous remark against the junior. While junior may suppress his/her feelings at that time, they give vent to it when they get opportunity. Those who witnessed this incident must have appalled. These incidents may appear small but have capacity to degrade the culture of the company!
Thanks,
