(Reuters) - United Parcel Service Inc , the world's biggest courier company, said on Thursday it ratified a five-year contract with higher wages and benefits for 125,000 unionized employees represented by the International Brotherhood of Teamsters. The company said it expected to take a pre-tax charge of about $1.05 billion in the second quarter due to the health and welfare changes in the newly-ratified plan.
