USPS sets the record straight
There is no ‘war’ on custodians at postal facilities
Recent assertions have been made that the Postal Service has “declared war” on the custodians who work in its facilities. These assertions are both false and inaccurate.
Here are the facts: The Postal Service is becoming more efficient in all areas of its business, including the way postal facilities are cleaned and maintained. 
Last year, USPS launched a pilot program to determine whether there were smarter, easier and more efficient ways to clean facilities. New cleaning methods, supplies and equipment were tested. USPS managers were pleased with the results.
In January 2014, consistent with requirements under the collective bargaining agreement with the American Postal Workers Union (APWU), the Postal Service provided notice of its intention to invoke the negotiated process to change relevant handbooks and manuals to implement the proposed changes.
Adhering to a negotiated process to implement change should not be construed as a “war” on custodial staff. Rather, this process allows the Postal Service and APWU to discuss all relevant issues regarding the proposed changes that USPS believes will ensure its facilities are cleaned in a more efficient manner.
