Shortly after the Marlins lost, 4-2, to the Mets on Wednesday, Guillen was informed the team will step back, let emotions settle and make a decision on the manager and the coaching staff.
A final decision may not come for a week or a few weeks.
"I expect to come back. I'd love to come back," Guillen said. "I think it's another opportunity, but at the end of the day, it is what it is. We have to look and see what's going to happen, but right now, I'm still a Marlin and I'd love to be a Marlin.
"Like I said, the kind of year we had, you never know. The expectations should be too high for me, my coaching staff or any of the players. That's what it is."
The decision ultimately will be made by Marlins owner Jeffrey Loria, who has yet to reveal his decision.
Not only Guillen's fate is at issue. So is the status of the coaching staff. There is a chance Guillen will stay, but his coaches will be replaced. The contracts of bench coach Joey Cora, hitting coach Eduardo Perez, pitching coach Randy St. Claire, first base coach Gary Thurman, third base coach Joe Espada and bullpen coach Reid Cornelius are all up.
So the team technically may opt not to renew some or all of the staff.
A season that started with such high expectations turned into one of the most frustrating in franchise history.
Guillen is under contract through 2015, and he's set to earn $7.5 million over the next three years.
On Thursday, Guillen and his wife are scheduled to be on a flight for a vacation in Spain.
"Am I going to lose sleep for that?" Guillen said. "Or am I going to worry when I'm on vacation having dinner with my wife about if we're going to be in Miami next year? It ain't going to happen."
In recent weeks, Guillen has had numerous conversations with Loria about the status of the ballclub. The manager said he has not received any indication that his job is on the line.
"If I'm back, I have to make this thing better," he said. "How's it going to happen? Working harder. Maybe teaching them a little bit more. Maybe know the players a little bit better. Maybe expect better things out of the players. There's a lot of things. I don't worry about getting fired."
Guillen has accepted his share of the blame for what happened this year. The Venezuelan native came to Miami with the expectation of guiding the team into contention. It never happened.
Should the Marlins move in another direction, Guillen admits it would hurt his pride.
"Yes, I'd be embarrassed," Guillen said. "Yes, I'd be ashamed of myself. I've got a country to represent. I've got a family. I represent baseball. You don't want to get fired, no matter what you do in life. You will be embarrassed, no matter what you do.
"I'll be at the Winter Meetings, either with the team, or without the team. I will be at the Winter Meetings, either managing the Marlins, or at the Winter Meetings looking for a job."
