Hi Sanjay
According to me your concerns are:
1. No training – Company had preferred you as a trainee and given you opportunity for on job training. On job training is most used and effective method of training. Sometime due to various reason organizations do not use other methods of training. It doesn’t mean that they are not training there key assets. Same time continuous learning and development is responsibility of employee also so try to learn as much as from your seniors, colleagues, friends, online, books etc. Try to understand the need of business and your role and focus on it. You will get positive result.
2. Mental Harassment – It is subjective and without knowing the actual facts of the case commenting on it will be not right.
You are new in organization learn fast, work hard and show result. There is well known proverb “Trust and respect are two things which everybody have to earn.” In spite of all your efforts if things do not improve or you are not happy then it’s time for change.
“Life is too short to wake up with regrets. So love the people who treat you right. Forget about those who don’t. Believe everything happens for a reason. If you get a chance, take it. If it changes your life, let it. Nobody said life would be easy, they just promised it would most likely be worth it.” ― Harvey MacKay
Welcome to corporate life and best of luck.
