11. Furthermore, the Employer's stance that there was never a direct employer-employee relationship is wholly unsubstantiated. If, in fact, the Appellant Workmen had been engaged solely through a contractor, the Employer would have necessarily maintained some form of contract documentation, license copies, or invoices substantiating the contractor's role in hiring, paying, and supervising these workers. However, no such documents have been placed on record. Additionally, the Employer has failed to establish that wages were ever paid by any entity other than its own Horticulture Department, which strongly indicates direct control and supervision over the Workmen's day-to-day tasks is a hallmark of an employer-employee relationship. Had there been a legitimate third-party contractor, one would expect to see details such as tender notices, contract agreements, attendance records maintained by the contractor, or testimony from the contractor's representatives. The absence of these crucial elements undermines the Employer's claim of outsourced engagement. In fact, it appears that the Workmen were reporting directly to the Horticulture Department officials, receiving instructions on their duties, and drawing wages issued under the Municipality's authority. This pattern of direct oversight and wage disbursement substantially negates the narrative that they were “contractor's personnel.” Consequently, the discontinuation of their services carried out without compliance with statutory obligations pertaining to notice, retrenchment compensation, or approval under Section 6E of the U.P. Industrial Disputes Act, stands on precarious ground. The very foundation of the Employer's defense (i.e., lack of an employer-employee relationship) is not supported by any credible or contemporaneous evidence.
