Convert Access SQL to SQL Server SQL

Below are my two query's top is from Access bottom is from SQL Server.  I know the access query is correct, but for some reason they are both returning different values.  What did I type incorrectly in my SQL Server conversion query/

--Access SQL
SELECT Count(SalesTickets)
FROM tbl_TotalSalesInfo
WHERE (((employeeName) Not Like "*Man*"))
OR (((employeeName) Like "*Man*") AND ((disSign) Is Not Null));

--SQL Server SQL
SELECT
COUNT(CASE WHEN (employeeName NOT IN ('Manager')) OR (disSign IS NOT NULL AND employeeName IN ('Manager'))
THEN SalesTickets ELSE NULL END)
FROM TotalSalesInfo
