The striking employees of a beer can maker are again calling on consumers to buy their brew in bottles.

The United Steelworkers union is setting up information pickets at beer stores across the province this weekend. It wants consumers to choose bottles to put pressure on can maker Crown Holdings, where some 125 of its members have been on strike since September 2013.

The Crown Holdings plant in Toronto produces about 5.5 million aluminum beer cans every day for companies like Molson Coors and Labatt.

​The union says employees walked off the job due primarily to disagreements over a two-tier wage system the company wanted to introduce.

Under the proposed system, new workers would make considerably less than those already working at the factory.

"We need to protect good unionized jobs in this province and in this country," USW official Mark Rowlinson told CBC News. "And by cutting back their wages by 30, 40 or 50 per cent, that prevents these folks from actually earning a living."

Crown Holdings declined a request for an interview.

The union made a similar appeal to the public last fall with a series of radio ads and a YouTube video.
