After a playing career spanning almost 20 years, Jackson went on to manage his former clubs Huddersfield Town and Bradford City. He also bossed Lincoln City, and it was during his reign at Sincil Bank that the Yorkshireman was diagnosed with throat cancer.
Jackson underwent successful radiotherapy, after which he took over at Valley Parade. However, his stay at Bradford lasted only six months and Jackson - who now enjoys a successful career out of the game - believes the pressure on modern-day managers to deliver immediate success and the scrutiny they are subjected to on the internet is too much.
In an interview with Sky Sports News Radio, Jackson said: "There is the old saying by Bill Shankly: 'Football is not a matter of life and death. It's more important than that.'
"Football is not life and death. Football is a defeat on a Saturday.
"I started in management in the 1996/97 season and the average span for a manager was two years and three months. Now, I think it's just under 10 months, which is incredible.
"I put that down to social media. There is a lot more publicity around football than there ever was - talk shows, letters into the local paper and websites have put a lot more pressure on managers.
"All it starts with is 'Jacko out' after one defeat and people jump on it. Directors and chairmen say they don't look, but they do, and I think that's a big factor."
Jackson also believes the vast sums of money swirling around the game are contributing to the pressure on bosses.
He said: "There is a lot of cash involved and everyone wants success. There was pressure on David Moyes in midweek and he's five or six games into his new job!"
