Hi, so here is the whole story,
on may 1st 2017 I started to work for a brokerage as an IT and Marketing manager. Before being hired I spoke with the brokerage owner and we discussed my payment etc. He said I would be paid $12.50 and hour from 10am to 6pm Monday to Friday. He also said my hourly payment would increase $1 per every 20 new agents that join our brokerage. He said that he would not pay me for the first 6 months, and that on the 7th month I would be paid and throughout the next 4 years I would be paid back the salary owed from the first 6 months. For the 3 months I worked there I did various things such as creating an online booking systems, an online invoice to pdf system and I also worked on the website. On July 28 he met me and said he wanted to change my contract and only pay me on a project to project basis since he realized I was not fit for the job. I told him I do not want my contract to be changed. He insisted that that would be the only way I could still work for him. I told him that I do not agree with these terms and that I cannot work with him anymore. I asked to be payed my salary for the first 3 months that I worked for full time. He now insists that I work for free to further finish everything he asked for and then he will give me the money owed. I told him that is not fair since I worked for him full time and he says now that it was not full time it was a project to project basis from the start. Unfortunately we did not sign a contract or anything about this but we have sent many emails and texts back and forth confirming that I was working full time and getting paid hourly instead of by a project to project basis. My employer had also hired another person as an administrator and he fired her 1 month later without giving her pay as well saying that she worked as a volunteer all of a sudden. I just want the money that I was owed which should be about 6k and I want to be done with this. Do I have a case or should I go back to him and finish everything for free and then get paid even though I think he might now even pay me then.

So my question is do I have a case? Is it even worth it sue? And what can I do do better my chances if I have a case since my employer thinks that I am ok with him we are still on good terms at the moment?
