2. The following circumstances are revealed as to whether Plaintiff E is the Defendant’s employee, Gap evidence Nos. 18 and Eul evidence Nos. 1; ① the Defendant issued a career certificate to Plaintiff E that the Defendant worked for Plaintiff E from February 1, 1973 to October 1980; ② the above period overlaps considerably with the working period claimed by Plaintiff E; ② in light of Plaintiff E’s name, Plaintiff E appears to be relatively clear that the asbestos disease occurred due to asbestos, and there seems to be a little reason for Plaintiff E’s claim against the Defendant even after referring to false working conditions. On the other hand, Plaintiff E’s working period is 1973 and 40 years have passed, and there is no possibility that the Defendant did not keep the working records in the form of document; ③ Plaintiff E was in charge of white asbestos joint work, Plaintiff E’s work, wearing a garch at the work site, but its operation could not be acknowledged in light of the contents of Plaintiff E’s work and other details.
