A 53-day strike at Casino Regina took its toll on revenues, according to information released Tuesday.

Employees at the Regina gambling venue walked off the job June 3.

"Due to strike action at Casino Regina ... guest counts at Casino Regina decreased year over year by approximately 30 per cent," the Saskatchewan Gaming Corporation, or SGC, reported Tuesday.

SGC is a provincial Crown corporation, which owns and operates two casinos for the Saskatchewan government, one in Regina and another in Moose Jaw. The Moose Jaw venue was not affected by the job action.

In Regina, managers kept slot games running during the strike, but reduced the casino's hours. Table games and a restaurant were closed.

According to the financial results for the first half of 2010, which includes a portion of the time Casino Regina was without its unionized workers, SGC saw a decrease in revenues.

SGC reported that the full impact of the strike had not yet been calculated.

However, for the three-month period of April to June 2010, gaming revenues were down $4.3 million, compared to the same time period in 2009.

On the other side of the ledger, expenses were also down because the wage bill was lower. In the April to June period, costs decreased $1.27 million, compared to 2009.

The full impact of the strike is not expected to be known until SGC releases a third-quarter financial statement, later this year.

The government has given SGC a net income target, for 2010, of $50.5 million. The corporation said Tuesday it will not reach that goal.

Two sets of employees walked a picket line during the labour dispute. About 465 members of the Public Service Alliance of Canada, which represents card dealers, slot machine attendants and security personnel, were in a formal strike action.

Another 240 workers, members of the Retail, Wholesale and Department Store Union, also joined the picket line in support of their union colleagues.

Both unions eventually reached new collective agreements with SGC and everyone returned to work July 26.
