I'm hired in company A(June2015), then after more than a year, they build a new company B(Joint venture with 1 other company C) and made us sign a contract(Sept 2016) that states we will get what we have in our previous company. We didn't get any separation pay since verbally they said that it's just a continuation of our previous job. But the problem arises when we discovered that the company B is not yet registered in SEC, as a consequence, our sss, pagibig, philhealth and tax has not been payed by company B, but it was deducted to our salary. By June 2017, they come up with evaluation and rate me most with 1(lowest) even though i'm doing more than my Job title, and give me 1 month to do a lot of jobs to save my position. After the evaluation, they want us to sign another contract that states we have to be a consultant employee of company C. I decided to resign last June 21, 2017 but they didn't acknowledge in the email although they verbally know. They already give the refunds of last years deduction (sss pagibig philhealth and tax). Now, I'm after my 13th month pay, and tax refund since they deducted taxes(which they did not pay to BIR due to the SEC issue) last Jan-June 2017, but they are pointing finger to one another this time that i think, they're ignoring my follow ups. I'm also worried of how I will be affected by the unpaid taxes from BIR.
What could be my legal actions towards this situation?
