We pass upon the present petition for review on certiorari 
seeking the reversal of the January 23, 2008 Decision 
and the February 27, 2008 Resolution 
of the Court of Appeals (CA
) in CA-G.R. SP No. 101069. The Antecedents
Summarized below are the relevant facts on record.
On November 21, 2003, respondent Bella Agcaoili-Barit filed a complaint 
for non-payment of salaries and refund of transportation fare against the petitioner Jones International Manpower Services, Inc. (agency
), owned and managed by Edward G. Cue.
Barit alleged that she entered into a two-year employment contract (July 23, 1999 to July 23, 2001) with the agency, for its foreign principal in the Kingdom of Saudi Arabia, Mohamad Hameed Al-Naimi (Hameed
), as a domestic helper with a salary of US$200.00 a month. She did her job diligently and with dedication, but was paid only US$100.00 a month and, starting January 2001, was not paid any salary at all. She extended her employment for another 10 months upon Hameed's request as her replacement had not yet been deployed by the agency. Hameed refused to pay her salaries even during the extension.
Fed up with her situation, she left Hameed on May 29, 2002 and had a live-in relationship with another Filipino overseas worker, Thomas Ambrosio, allegedly her boyfriend. As the law of Saudi Arabia prohibits such a relationship, she was arrested and imprisoned for more than a year. She claimed that she embraced the Islam religion and was exonerated of the charges against her. She was released from prison on October 14, 2003 and immediately left for home, arriving in the Philippines on October 15, 2003. She demanded payment of her salaries for one year and four months, payment of wage differentials from July 1999 to December 2000, and the refund of her airfare to the Philippines.
In defense, the agency argued that Barit's contract of employment expired on July 23, 2001, without any complaint from her. Her contract was extended for another two years with her consent. It alleged that Barit left her employer without permission. She was then reported missing to the Saudi police who found her staying with Ambrosio. She was subsequently arrested and imprisoned. Hameed was helpless in providing Barit assistance because she violated marital law and the offense was non-employment related. Her passport, air ticket and the balance of her unpaid salaries were turned over to the Saudi authorities pursuant to Saudi law.
The agency denied liability for Barit's alleged unpaid salaries beginning July 2001 as her employment contract, which it facilitated, was only for two years. The contract expired on July 23, 2001. It maintained it had no involvement or participation in the alleged extension of Barit's employment with Hameed. It also argued that it had no liability for the refund of her airfare to the Philippines.
The agency argued further that it was not also liable for Barit's alleged wage differentials from July 1999 to December 2000 and unpaid wages from January 2001 to July 23, 2001. It pointed out that all wages due her were paid in full, while the final wages due her before she left her employment were turned over to the Saudi government. It stressed that it was highly illogical for Barit to agree to an extension of her employment contract with the same employer who, she claimed, had not paid her salaries and underpaid her wages in the past two years of her contract.The Compulsory Arbitration Rulings
On March 31, 2004, Labor Arbiter Nieves Vivar-de Castro found Barit's money claims meritorious. 
She directed the agency and its foreign principal to pay Barit salary differentials from July 23, 1999 to December 31, 2000 and her unpaid salaries from January 2001 to July 23, 2001. The labor arbiter, however, absolved the agency of liability for Barit's alleged unpaid benefits during her second or extended employment as it did not participate or intervene in securing this extended posting.
The agency appealed to the National Labor Relations Commission (NLRC
). In its decision dated August 28, 2006, 
the NLRC granted the appeal. It set aside the labor arbiter's ruling and dismissed the complaint, but awarded Barit financial assistance of P10,000.00 "for reasons of equity." In the main, the labor arbitration body rejected Barit's submission that she was compelled to leave Hameed because he had been underpaying and was not paying her salaries. The NLRC did not believe that she would agree to continue working for the same employer for another ten (10) months, when the employer had not been paying her salaries before and during her extended employment.
Barit moved for reconsideration, but the NLRC denied the motion in a resolution dated March 30, 2007. 
She then sought relief from the CA
through a petition for certiorari
, charging the NLRC with grave abuse of discretion in setting aside the labor arbiter's decision, and in holding that the agency is not solidarily liable with her employer for the underpayment and non-payment of her wages.The CA Decision
In its decision of January 23, 2008, 
the CA found that the NLRC committed grave abuse of discretion in setting aside the labor arbiter's decision. It upheld the labor arbiter's award to Barit of salary differentials from July 23, 1999 to December 31, 2000 and unpaid salaries from January 2001 to July 23, 2001, to be paid solidarily by the agency and its foreign principal. It brushed aside Hameed's defense, through his letters dated November 15, 2003, 
January 21, 2004 
and February 28, 2004, 
that he had fully paid Barit's salaries since day one of her employment. It declared that absent any evidence, such as payrolls, payslips or acknowledgment receipts, Hameed is deemed to have failed to discharge the onus probandi
Its motion for reconsideration turned down by the CA, 
the agency now appeals to the Court by way of the present petition for review on certiorari.The Petitioner's Case
Aside from the petition itself, 
the agency submitted a memorandum, 
as required by the Court, 
and a reply 
to Barit's comment.
Through these submissions, the agency asks for a reversal of the CA decision on the ground that the appellate court erred in (1) affirming the labor arbiter's award to Barit of salary differentials from July 23, 1999 to December 31, 2000 despite the non-inclusion of the claim for underpayment of wages in the complaint, in violation of the NLRC Rules of Procedure; and (2) disregarding the "other similar documents" the agency submitted to the labor arbiter to prove that Barit was fully paid of her wages.
On the first issue, the agency cites Section 7(b) and (d), Rule V of the 2005 Revised Rules of Procedure of the NLRC, as follows:
b) The position papers of the parties shall cover only those claims and causes of action raised in the complaint or amended complaint excluding those that may have been amicably settled, and accompanied by all supporting documents, including the affidavits of witnesses, which shall take the place of their direct testimony.
d) In their position papers and replies, the parties shall not be allowed to allege facts, or present evidence to prove facts and any cause or causes of action not referred to or included in the original or amended complaint or petition.
The agency argues that the labor arbiter ignored these rules when she took cognizance of Barit's claim for wage underpayment which was mentioned only in the latter's position paper. It points out that in the complaint 
Barit filed with the NLRC, she underlined only (1) non-payment of wages and (2) refund of transportation fare as her only causes of action. It posits that the labor arbiter and the CA both erred in ignoring the rules.
On a different plane, the agency contends that the award of salary differentials to Barit has no legal basis as she herself admitted that she received a monthly salary of SR600 that, if converted to US dollars in 1999-2000, was equivalent to US$200.00, thus negating the claim of underpayment of wages.
The agency insists that Barit's wages had been paid in full as evidenced by the letters 
of Hameed which show that all the salaries and other benefits due Barit, including her passport and other belongings, were paid and given to her before she was released from jail and repatriated to the Philippines, in accordance with the laws of Saudi Arabia. The agency bewails the CA's failure to give due consideration to what took place after Barit left her employer in May 2002. Barit was then apprehended by the authorities of Saudi Arabia for living-in with a man who was not her husband. She was imprisoned for having committed a marital offense and was discharged only after she served out her sentence, not exonerated by the court as she claimed. It further contends that the CA failed to give consideration to the policy of the government of Saudi Arabia not to allow the release of foreign workers from prison without their employers paying all their salaries and other benefits, as well as releasing all their personal belongings.The Case for Respondent Barit
Through her comment 
and memorandum, 
filed on June 27, 2008 and October 22, 2008, respectively, Barit prays that the petition be denied for lack of merit.
On the first issue, she argues that the agency resorted to hairsplitting or pure semantics in denying liability for her claim of underpayment of wages. She refers particularly to the agency's contention that wage differentials should not have been awarded to her because she did not include underpayment of wages as a cause of action in her complaint. She insists that the complaint form that she accomplished shows that her cause of action was for non-payment and underpayment of wages as the two terms appear in only one box. In any event, she explains that "to underpay," 
means "to pay less than what is normal or required." Since she was paid only half of her wages, there was an amount that was not paid and this was the other half of her wages. There is, therefore, non-payment of this other half. She posits that in this context, she was correct in pursuing her claim of underpayment of wages.
On the issue of non-payment of wages, Barit maintains that the CA committed no error in ruling that the agency failed to present substantial evidence to prove due payment of her wages while she was under the employ of Hameed. She takes offense at the agency's submission that the issuance of monthly payslips or the keeping of payrolls is seldom or rarely done in the case of domestic helpers. She argues that with this reasoning, the agency would be placing domestic helpers in a different category of workers, a distinction which is repugnant to the Constitution.
Barit further argues that the burden of proving payment of what is due the employee is upon the employer and, since she is an overseas worker, also upon the employer's recruitment agency. She contends that her employer's letters, 
purporting to show that her salaries and other benefits had all been paid, are self-serving unofficial statements that have dubious evidentiary value. She reasons out that such letters, which were mentioned in the case cited by the agency in its submissions, 
cannot be considered as "other documents" for nowhere in that case was the term "other documents" discussed and neither did the ruling give an example of "other similar documents that have the same force and effect as payrolls, employment records and remittances." 
In the absence of evidence proving payment, Barit submits that her employer and the agency are solidarily liable for the award, pursuant to the law and the rules.
Finally, Barit takes exception to the agency's argument faulting the CA for disregarding other relevant circumstances in the case, such as the completion of her contract without the filing of any claim for unpaid or underpaid salaries on her part, and her supposedly voluntary act of renewing her contract and living-in with another Filipino worker which led to her imprisonment. She maintains that these circumstances, even if considered, do not change the fact that there has been gross violation of Philippine laws by her employer and by the agency, for which they should be made solidarily liable. She explains that she was forced to act because of the long suffering inflicted on her by her employer who refused to pay her salaries in full and compelled her to extend her contract for another year.The Court's Ruling
The Court, as a rule, 
is bound by the factual findings of the CA, but has the discretion to reexamine the evidence in a case when a basic conflict exists between the CA's findings of fact and those of the NLRC. 
In this case, such conflict exists and we need to reexamine their findings to determine: (1) whether Barit had been underpaid and/or had not been paid her wages during her employment in Saudi Arabia; and (2) whether the agency is solidarily liable with the foreign employer if Barit is indeed entitled to her money claims.We find merit in the petition
Under the circumstances of Barit's employment in Saudi Arabia, we wonder how she could have and why she remained in the service of the same employer for a considerable period of time if she had been underpaid her salaries or had not been paid at all, and why she had kept silent about her salary situation. Nowhere in the records does it appear that Barit complained about the alleged underpayment and non-payment of her wages with the Philippine labor or consular representatives in Saudi Arabia, or even with the Saudi authorities themselves. Neither is there any showing too that she ever objected to or protested her iniquitous work situation directly with Hameed, if that had really been the case, nor that Barit identified or spoke of any problem that could have prevented her from seeking relief in Saudi Arabia, as the NLRC noted. 
Barit abruptly left her employer, not because she was being exploited with respect to her wages, but for a personal reason -- she left in order to live with her boyfriend Ambrosio. As a consequence of what she did, she ran afoul of the law of Saudi Arabia.
This analysis leads us to conclude that the NLRC's conclusion is not without basis; substantial basis exists to believe that Barit received her full salaries for the entire duration of her original contract, or from July 23, 1999 to July 23, 2001. The NLRC further opined that to make the agency liable for Barit's alleged unpaid and underpaid wages on the sole ground that it failed to submit copies of payslips and payrolls is unfair as the agency appears to have taken all available means to secure the necessary documents from Barit's employer to dispute her claims. The NLRC stressed that the labor arbiter should have considered other factors in resolving the case.
The records support the NLRC's appreciation of the merits of Barit's claim. As early as September 28, 2002, the agency inquired with Barit's employer how she was faring in Saudi Arabia, in relation particularly to the case brought against her by the Saudi authorities and to her unpaid salaries. 
The inquiry was prompted by Barit's mother's inquiry about her situation in Saudi Arabia. On October 3, 2002, the agency received an answer from Hameed 
advising the agency's President, Edward G. Cue, that Barit had left his residence and was discovered by the Saudi police to be living with Ambrosio and that Hameed could not intervene as she committed "a crime related to martial (sic) affair." 
Hameed also informed Cue that Barit's passport and air ticket, and the balance of the money due her were handed over to the authorities, pursuant to the law of Saudi Arabia. Additionally, Hameed intimated that if necessary, the agency could seek verification from the Philippine Embassy in Saudi Arabia about what he reported to Cue.
On November 15, 2003, the agency received another letter 
from Hameed in response to Cue's overseas call regarding Barit's unpaid salary. Hameed again informed Cue that "[t]here is no more pending salary with us, all her personal belongings were turned over to the police as this is the law here in Saudi Arabia." Hameed also told Cue that Barit finished her two-year contract and she could not have signed another contract with him if she had not been paid her past salaries.
On November 21, 2004, Hameed again wrote Cue 
informing the agency official that as he said in his previous letters, "everything has been paid to her" and that the Saudi authorities will not release her from jail unless everything is settled, for the Saudi government is very strict when it comes to unpaid salaries.
In light of this exchange between the agency and Hameed, and the real reason why Barit left Hameed's employ, we are as convinced as the NLRC that she had been paid her salaries in full for her first employment contract (which the agency facilitated), from July 23, 1999 to July 23, 2001.
The argument that absent the payslips or payrolls, the agency failed to present proof of payment of Barit's claim should be viewed in the context of the realities of domestic service. The relationship between Hameed and his family, on the one hand, and Barit, on the other hand, was largely confined within Hameed's household. It was not as structured as the relationship obtaining in an office or in an industrial plant. There was very little or no paperwork at all, even on wage payments. As the NLRC opined:
Just like our local domestic house helpers who receive their wages directly from their employers without any payslip or voucher to acknowledge payment and receipt, we do not expect the case of herein complainant x x x to be any different. It is, therefore, understandable that no payslip or payroll could be presented by respondent agency. 
We find this NLRC view to be a fair and credible assessment of the employment relationship between Barit and her Saudi employer, at least, in relation to the payment of Barit's wages.
In sum, we hold that the NLRC committed no grave abuse of discretion in dismissing the complaint. The CA thus erred in granting the petition for certiorari.WHEREFORE
