ICM, a friend of mine was a ch tech in Ceylon as I recall.
Apparently it was not a strike or a mutiny where they were. A new adjutant was posted in and set about restoring order and discipline, little things like wearing berets, smart uniform, a daily parade before start work, all good military things designed to improve morale and spirit de corps.
The chaps didn't parade but went directly to work. Naturally word of this spread to AHQ and VSO arrived, had a locked door interview with the troops, order was restored and the adjutant was posted.
Shades of our OC Admin in ASI in 1984, headdress will be worn, only the sqn ldrs and the gp capt did.
