In a statement, the Guild said basic security and protection from arbitrary action are essential if senior journalists are to go about their task with "courage and fairness."
Gupta, Managing Editor Charles Assisi, Executive Editor Shishir Prasad and Director (Photography) Dinesh Krishnan had worked with the magazine since its inception and their "sudden removal without resonable notice and even elementary courtesy cuts at the very root of editorial independence," it said.
"Considering that senior journalists are involved in the dispute with a media house, the Guild would reiterate at this stage that it is essential that all contracts should be honoured," the statement said.
