My partner and I are [company] employees who finished securing Aircraft X on Gate XX. We were about to call for deadhead when my partner noticed that the wing of Aircraft Y; being pushed out by [company] from Gate XY; was coming very close to our aircraft's tail and Number 1 side rear stabilizer. I got out of our Supertug to signal an 'X' with my arms (to stop the aircraft); but the pushback driver did not stop. Only after my partner called Ramp to tell the pilots to stop the pushback process did the mechanics stop the push. The pushback driver stopped the push for a brief period of time before continuing and finishing the push. There were also no wing-walkers utilized during the pushback of Aircraft Y by [company].
Ground Crew reported company mechanics pushing back an aircraft without wing-walkers that came close to touching the reporter's aircraft.
