Hello, I recently joined an organization two months ago. The work was different from my previous experience, which I had already informed them about. Everything was fine initially, but later the boss started being rude for very trivial reasons and mistakes. She began singling me out, even though the same mistakes were made by my other colleagues. At one point, it became too much, and I decided to resign. Fortunately, I found a job at a different organization. Now, my previous boss is targeting me even more. My new organization requires an experience letter, so I am serving the notice period. However, I am worried that she may not provide me with the experience and relieving letter on my last day.
