Case Summary (G.R. No. 159507)
Background of Employment
Manuel Arianza was employed by Central Azucarera de la Carlota, Inc. in 1960, having been deemed fit for work following a thorough medical examination. He worked various positions for a total of ten years, including packing bagasse and serving as a piler and water tender in the mill department. His job duties involved strenuous physical exertion and exposure to adverse working conditions, such as being half-immersed in hot water during his last assignment.
Health Issues and Illness
Arianza noticed a decline in his health beginning in 1965, which he initially did not take seriously.

The presumption of a causal connection between the employment and the illness remained unchallenged by credible evidence from the respondents.
Employer's Burden of Proof
Notably, the ruling established that once an employee demonstrates an illness that arose during the course of their employment, the burden of proof shifts to the employer to disprove the connection. In this case, the company's physician's opinion that the claimant's exposure to heat and cold did not cause his illness was insuffici
