Most resignations are fairly straightforward: Employees give you written notice of their intentions to leave the company, and two weeks later they’re gone. However, many companies with salespeople ask account executives to leave the same day that they give notice. The logic there is that salespeople who are leaving to join the competition may bring sensitive client information with them.

It’s also the case that managers sometimes feel that certain nonsales
employees are better off leaving that same day that notice is given. The reason? If those employees are perceived to be troublemakers,
if they have access to sensitive company information (especially information systems or finance employees), or if they appear to have mentally checked out, then having them around may be a morale or security problem.

In such cases, it is certainly acceptable to ask employees to leave the day they give notice. After all, they’ve already given notice of their intention to leave your company, haven’t they?Wait—there’s a catch here. If this is done incorrectly, you could be exposing your company to unnecessary liability.

When employees give notice of resignation, they are technically seen as the ‘‘moving party’’ in the termination. They have the right to give two weeks’ notice and work through those two weeks, especially if your company states in its handbook that it expects employees to give two weeks’ notice upon resignation.
