work hours? what yall think?

I work at a factory where we make axles for 18 wheelers. We are really short handed and I have the opportunity to come in or stay over 4 extra hours. I'm currently working 8 hours a day and 6 to 7 day weeks. I make $14 and hour and its time and a half anything over 40 hours. so thats like $21 an hour and Sunday is double time $28 an hour. My pay check is pretty fat around $900ish a week, but if I work the extra 4 hours a day that will add another $2K to $2.5K to my pay a month after taxes. I really need the money to get my truck back together. At the same time its taking away time from my wife and son. I lack another month from getting my vacation, so what yall think, take the opportunity and take some vacation for my family, or stick to my same hours?
