West Bromwich Albion boss Alan Irvine admits the sack race is difficult to avoid.
They host West Ham on Tuesday having won just once in their last eight games in all competitions and Irvine insisted there are too many outside pressures on managers.
"There are, it's well known it took Sir Alex Ferguson a long time to have the success he had," he said.
"In today's climate he wouldn't have got anywhere and people wouldn't have seen the most successful manager in British football because he would have lost his job.
"That's where we are, it's an instant society. Everything is expected in a hurry."
And Irvine feels the wider audience do not understand what it takes to be a top-flight manager.
"Probably not," he said.
"I had a very long apprenticeship before I became a manager. I thought I knew what becoming one would be having spent five and a half years as an assistant manager and having done just about every coaching role.
"But I found out when I sat in the chair I didn't know.
"It's like people will think they know (a journalist's) job and, when they have done it, that's when they realise they don't know (what it involves). That's the way it is."
