Livingston chairman Pearse Flynn paid tribute to Paul Lambert, after the former Scotland international resigned as the club's manager.
Lambert announced his decision after his side's 1-0 defeat by Dunfermline left them six points adrift at the bottom of the SPL.
Flynn said: "We are deeply disappointed the club's results and league position contributed to Paul's decision.
"But we should also pay tribute to his dedication to the job since taking it."
Lambert only took over at Livi in the summer, but decided to leave for reasons he said would remain private.
Flynn added: "Paul Lambert left Livingston on Saturday with great dignity and professionalism.
"Paul had become a friend as much as he was our manager and I hope he has laid some worthwhile foundations, not least in championing some of our younger players who have broken into regular first-team football this season.
"Livingston are bottom of the league, but everyone at the club will be doing their utmost to fight for every point between now and the end of the season.
"There are still 12 games to go - nearly a third of the season - and every effort will be made to improve on our current league position."
