Relationship dissolution is common among socioeconomically disadvantaged parents. This study utilizes longitudinal data from the Fragile Families and Child Wellbeing Study (FFCWS) to assess whether fathers' time off work after the birth of a child reduces the likelihood of parents dissolving their relationship. We also consider whether the association between fathers' time off work and relationship dissolution is mediated by fathers' support of mothers and moderated by union type. Results indicate that the risk of relationship dissolution is lower when fathers take time off work after the birth of a child. Results also suggest that longer periods of time off work (i.e., two or more weeks) are associated with a lower risk of relationship dissolution among married couples, although overall evidence for variations by union type are mixed. Additionally, there is evidence that the association between fathers' time off work and relationship dissolution is at least partially explained by higher levels of relationship support among fathers who took time off work after the birth of a child. Overall, findings suggest that providing fathers with opportunities to take time off for the birth of a child may help to promote relationship stability among socioeconomically disadvantaged couples in the U.S.
