Again, Art 26 Sec 1(a) "... During peak season, the Employer will make every reasonable effort, in accordance with the appropriate Supplement, Rider or Addendum, TO USE CURRENT UPS EMPLOYEES and hire a sufficient number of employees to handle peak volume. AFTER doing so, the Employer may use alternate means of transporting packages during peak season and will utilize union carriers whenever possible. Plans to utilize outside carriers will be reviewed and agreed with the Local Union. Such agreement will not be unreasonably withheld."
