Members of the Rail, Maritime and Transport union will walk out from 5pm on July 12. They will also ban overtime over the weekend of July 10-12. The move follows a 9-1 vote for strikes among union members at Southern, which operates commuter and other services between London and the Sussex coast.
The RMT said hundreds of engineers were involved in the dispute and warned that the strike will hit services. Officials said under the 2013 pay settlement, a working group of union reps and managers was set up to find productivity measures that could cut the working week.
The union said the group could not find any way to bring in a 35-hour week with no extra cost to the company. Productivity measures were subsequently brought in for engineers without leading to a reduction in the working week, said the RMT.
General Secretary Mick Cash said: "RMT will not stand by while agreed policies, procedures and agreements are unilaterally ripped up by Southern and promises on the reduction in the working week are kicked aside despite increases in productivity.
"As a result we declared a dispute and our engineering grades have now delivered a massive vote for industrial action and that programme of strikes and overtime bans will begin next week.
"In all of this, management have failed to show our members the respect they deserve as skilled and dedicated workers. We have made every effort to talk to the company about these issues, but have got nowhere. The only option we have it to use industrial action.
"Southern is a company intensively under the spotlight over its performance at the moment and RMT will not have our members left unrewarded as they hit work targets and then face a barrage of attacks on working conditions and procedures. RMT remains available for talks."

The findings were published by the Airport Commission which took three years to reach its conclusion which looked at the best way to increase the country's airport capacity.

Members of Parliament from the south east have expressed their reaction to a report saying a third runway at Heathrow is the best option to increase the country's airport capacity.
The findings were published by the Airport Commission which took three years to reach its conclusion.

The Mayor of London, Boris Johnson, said today that a new runway for Heathrow would mean a massive increase in noise pollution and fumes.
David Cameron announced a short time ago that a decision on a new runway for the region would be made by the end of the year. The recommended option, announced today, is Heathrow.
Residents around Heathrow are furious over today's announcement that the airport is the preferred option for a new runway. Interviewees: Helen Hansen-Hjul and Murray Barter.
Members of the Gatwick Area Conservation Campaign have been celebrating after today's announcement. Heathrow is the preferred option for a new runway. The interviewee is Sally Pavey.
We are delighted that the Airports Commission, in seeking to increase airport capacity, has not opted for a further runway at Gatwick. This will come as a huge relief for thousands of residents in West Kent.
Kent would have suffered negative impacts in terms of increased aviation noise from more than a doubling of aircraft movements.
Aviation noise in West Kent from Gatwick’s current single runway configuration is already unacceptable and a potential doubling of this impact with a second runway would have been intolerable.
Adam Afriyie, the MP for Windsor, says he will fight the Heathrow runway plan 'tooth and nail'.
Former Concorde pilot Jock Lowe was behind the second Heathrow scheme to extend one of the runways. He has mixed feelings about today's recommendation.
