I got a new job 2 months ago and the pay was good given that I will be getting married and need to take of my mother's medical bills. I have a different salary during my probation and a higher one after it ends.
My new company had a probation for 2 months. In the first month, I wanted 2 days off to go home and I asked my manager if I could talk to him personally, and during the conversation he said, "I expect more from you as a senior developer and I'm not happy with your deliverable".
I told him that I may be upset about my mother's health but I have been putting long hours and finishing my work(My work exceeded the due date by 1-2 days.) He told me we can keep you here if we revise your salary. I told him salary revision is fine. (I was offered a 50% hike. Even if it reduced I would be content).
Later a month goes by and I ask him again if I am doing well. He said "I have not evaluated you but the tasks given to you were easy ones and I will revise the salary before probation ends". I said salary revision is fine and he asks for my previous company's pay slip.
He made my current salary same as my previous company's salary and credited the amount on first of this month, without sending me a new offer or me signing any document or any information even on Slack or E Mail.
I am also going to get married and I really liked this job, did not think of switching jobs again. I spoke to my manager about this and he is only willing to increase a little from my previous company.
He knows I need money and job hunting will take time. I feel he has royally screwed me over.
I thought there would be a negotiation at least. I never thought they would decide a number and I should just be okay with it. How do I deal with it now? What do I do?
My contract does not mention that they can revise my salary anytime without my consent. It only says I need to give a 2 months notice and that they also will give a 2 months notice.
