Prior to their dismissal, respondents demanded payment of their unpaid wages and protested the substandard conditions of their employment. The Letters of Indemnity supra contained a waiver by petitioner and Kara Seal of the right to institute disciplinary action against respondents. Hence, respondents were under the impression that they would be disciplinarily dealt with if they would not sign the waiver. Based on the foregoing disquisition, we are convinced that respondents were forced to sign the Letters of Indemnity. Thus, said Letters of Indemnity must be deemed void. The stamp and signature of the ITF representative thereon add nothing to render the letters of any legal effect, but instead add to the impression of pressure exerted by ITF on the individual Filipino seamen. Having ruled out voluntary resignation, we now ascertain whether respondents were illegally dismissed.  Try hard as we may, no clear showing could be found in this case of any valid and legal cause which justifies respondents’ removal from employment.  Instead we find that Oriental and/or Kara Seal did not serve two written notices to respondents prior to their termination from employment as required by the Labor Code.   Plainly, there was no due process in [19] their dismissal, and we have here a clear case of illegal dismissal. In this connection, paragraph 5, Section 10 of Republic Act No. 8042  provides: [20]             In case of termination of overseas employment without just, valid or authorized cause as defined by law or contract, the worker shall be entitled to the full reimbursement of his placement fee with interest at twelve percent (12%) per annum, plus his salaries for the unexpired portion of his employment contract or for three (3) months for every year of the unexpired term, whichever is less.
