Pennsylvania, like many other jurisdictions, has standardized guidelines pursuant to statute to determine the amount of spousal and child support that should be awarded by the court in a particular case. 

Once a support order is entered, a party may petition the court to modify or terminate the support order when there are material and substantial changes in circumstances to include changes in employment and/or emancipation of a child.  Voluntarily quitting a job, being fired for cause, or accepting a lower paying position will not have an effect on a support order. 

Depending on your situation, you may be entitled to receive support for both you and your children.
