Multiple Ids of table A referring to Table B how to set relationship?

I have a teams table which has following structure :

id | manager_id | leader_id | member_id |

All of these three ids i.e manager_id leader_id and member_id are referring to id of employees table how do I set relationship because usually I do :

public function functionName()
{
    return $this->hasOne('\App\Models\Employee', 'id', 'manager_id');
}

But not able to figure out in this case
