Human Factors; Procedure
I wrote up the Green hydraulic system as being over serviced. A mechanic came to the cockpit shortly thereafter and asked did you power up the Green hydraulic system and cycle the controls? I told him number one that won't fix the problem and number two that's not my job. He then left without saying anything. 5-10 minutes later another mechanic comes to the cockpit and says I'm going to power up the hydraulics and cycle the controls; to which I said don't you want clearance from ground to ensure nobody gets hurt around any moving parts? Ah; we do this all the time and nobody has gotten hurt. I then said stop what you are doing until I'm off the aircraft. I then stood in the jetway until they said they were done. I re-entered the cockpit to find the Yellow [System hydraulic] pump turned on. I turned the pump off. The potential to hurt someone via moving doors and flight controls is a concern.
