Hi, I am a bit stressed up..I don't know why this happened coming from a office colleague mam who is 5 years senior to me. I was deliverying a presentation to our business newcomers in our team but one of my colleague who is 5 years senior than me started cross questioning me massively in and out on the topic.. even though the business newcomers did not had any problem .. My manager told me that she was there to help ne but on the other hand shw was there pulling me down in front of everyone.. I somehow managed the whole presentation. but I am deeply disappointed on this incident.. I too am a new joiner with 6 months only in the organization and this activity coming from my own colleague who is senior and was there to support me.. makes no sense to me.. I never had done any wrong behavior with her.. or anything then why was she trying to put me down that too like this.. I feel really anxious after this.. ..
