Was instructed by Management to jack up aircraft. Was told that proper documentation for shoring aircraft was available; but I personally did not witness this authorization. Was advised by higher seniority mechanics to not jack aircraft; and did so along with them anyways. Environment for jacking aircraft was not adequate in my professional opinion as there was a slight decline to the left side of the aircraft. Overall felt unsafe and would not assure anyone of the aircraft being securely jacked/shored.
Maintenance Technician reports jacking an airplane without proper shoring.
