An interesting read.

Both parties are at fault.

a) When an employer promises you something such as raise etc get it in writing. Word of mouth is never credible although depends on the individual but why take chances?

b) He exploited and paid less but isn't that what you agreed upon while accepting employment? You thought it was lucrative offer since it was your first job. "something is better then nothing" in your own words.

c) Intervening in your personal life by calling your parents sounds ridiculous.

d) He is the manager. He runs the company. It would have been wise if you had left instead of trying to change the system. FYI welcome to the cooperate world this is how things work out in real life.

e) No point in hanging in there after you have lost all the interest and motivation to work for him only ending up writing a long defamatory article with graphics and creating a blog.

f) His management style sounds cost effective but sure he does not treat his employees right.
