Some people are suggesting you sue the employer, but based on what? Your foul language? The payroll clerk not being nice to you? Your being fired?
You cannot cuss at female employees, nor male for that matter without risking your termination. You did, they fired. Courts wouldnt rule in your favor.
She wasnt nice? If she isnt vulgar, you cant sue because of what she did. Courts would laugh at that.
You got fired? I would bet alot of money that they have a written "rules of conduct" that you probably signed a copy of when hired, and it would prohibit at the risk of termination abusive language or creating an intimidating atmosphere. Again, you are not justified as I see it to seek legal redress.
Someone said you can sue for free, hardly. And as far as the idea that a lawyer would take on your case for free, looking for a contingency payment, most lawyers only do this when they have reasonable expectation of a successful case or at least leverage for a settlement. I personally dont see it in this case.
Move on, be honest in future employment pursuits, and learn a lesson from this past situation.
good luck,
