It's a staple

Unions hate competition, and public employees' unions really, really, really hate it;

A postal-workers union is ramping up a campaign to try to slow the U.S. Postal Service's partnership with Staples Inc....including asking unionized teachers to boycott the chain and buy school supplies elsewhere.

Last fall, Staples began providing postal services under a pilot program that now includes 82 stores in California, Pennsylvania, Georgia and Massachusetts. The sites are staffed with Staples employees.

The American Postal Workers Union, whose members have average pay of just under $25 an hour, said it fears a broader rollout would end up transferring more duties to lower-paid Staples employees, cutting the need for neighborhood post offices and leading to post-office layoffs. 

Of course the USPS has been closing neighborhood post offices for decades, but never let the facts get in the way of your selfish interest.
