Settlement agreements are complex to negotiate, as the financial sum must be calculated and the agreement on other terms must be taken into account. A condition often negotiated is the payment and the employee`s notice period. You should consider creating a PEST if you are firing an employee and do not want them to participate in the work during their notice, perhaps due to concerns about permanent access to confidential information or business contacts or fears of inconvenient behavior. If you insert your notice as part of a transaction agreement, the money you earn during termination is, as usual, taxable as salary.
