You don't need any of that information stored in the Manager info table - you can get that all from your employee table.
You simply need the EmpID , the Managers EmpID, and the Level 2 Managers EmpID. Just because they are a manager doesn't mean they end up with a different email or phone number does it?
And if that changes you have to update all those fields, twice, rather than simply changing the ID you have stored.
If the level 2 manager is always the managers' manager this is superfluous.
