Wal-Mart took over all of Woolworth/Woolco operations in Canada. They shut down any Woolco stores that were unionized at the time. They have used closure or threat of closure as a weapon against employees ever since. They try to use the Michelin template to discourage any union activity. For the most part they treat employees well as long as they are a "team player" but there is little room for independant thinking. Do what you are told and keep your nose clean!
What I find more objectionable is them flooding their shelves with Chinese sweat shop products while manufacturing towns in North America are being abandoned. Wal-Mart is not totally to blame, of course, but if the shoe fits..............
