This is going to vary from state to state and depending on labor laws.
I was an operations manager at a 2 million company some years ago. An employee gave notice and said he was going to work for a compititor. The owner said find a reason to cut him loose , so when the next day he wrote his time down as leaving a 3:30 and the owner saw him driving down the road at 3:15, he said fire his ass. We did.
He got a lawyer and said he would sue us for unlawful termination if we did not pay him for the 2 weeks.The owners attorney said pay him and hope he still does not sue your ass for the unlawful termination.
Points in the employees favor:
1. No previous write ups or letters for ANY infractions of any kind in 3 years.
2. Company had no clear definition of infractions or progressive disipline policy that had been follwed.
3. Termination followed by one day employee giving notice to work for a compititor.
4. Employee did not have access to any type of confidential customer information.
Points in the employers favor:
None.....
I have a complete employee handbook, progressive disipline policy, infraction definition and progressive disipline form so that I am covered on all bases. Employee signs it upon hiring and we can live and die by it.
These deals are going to to vary from state to state, but in Oregon if you try to get the state labor board to help you, forget it for the employee, the state agencies are slanted to the employer. But if the employee pursues it in court civily, get your check book out, the judge or jury will hang the employer.
I would reccomend consulting a LABOR LAW attorney in your state before assuming anything, other wise your rolling the dice.
