re: Putting the wife on disability/unemployment when she is having a baby

Unemployment in a nutshell:

Once someone is no longer working, then that means one of two things happened:

1.) Employee left for whatever reason.
2.) Employer decided to make them leave for whatever reason.

If its option 1, then the burden of proof is on the employee to prove that they did not leave for disqualifying reason.

If its Option 2, then the burden of proof is on the Employer. They need to document or prove beyong a reasonable doubt that they separated the employee with good cause that rises to the level of misconduct.
In summation:

In every situation in which a formerly employed person is no longer working, there was a moving party. Whether it was the employer or the employee, they need to have good cause in the explanation regarding the reason for separation if they'd like to either avoid or collect Unemployment.

Applying a twisted knee or a pregnancy to the system will result in a disqualification. The pregnancy and the knee injury-provided it did not occur on the job-are not the fault of the employer, and they will not be held liable to pay benefits in that instance.
