(Reuters) - Teamsters Local 19 has reached a four-year tentative agreement with Southwest Airlines ( LUV ) that provides a 23% wage increase to flight simulator technicians, the union said in a statement on Thursday.

The agreement comprises improved retirement package and paid paternity and maternity leave, as well as significant ratification bonuses for the 54 technicians apart from the wage increase.

The union members will vote on the contract within the next few weeks, said Teamsters Local 19, which represents aviation workers throughout Texas.
