Motorists can take comfort that they won’t be left high and dry and gasoline pumps will keep flowing at Shell service stations across Alberta.That’s because the fuel retailer has struck a deal with unionized workers at its Scotford refinery near Edmonton.According to the Unifor union, members overwhelmingly approved a new four-year agreement that includes a 16% wage increase and increases in time off, holidays and various union-based leave.Shell did not immediately comment.That means work will continue unimpeded on its Polaris carbon capture project that was announced last week in partnership with Calgary-based ATCO.It also means there will be no work stoppage at the sprawling refinery and chemicals complex that processes about 320,000 barrels per day of oil sands from Fort McMurray.
