One of the ways to solve this crises from a public relations' perspective is: adopting a slogan for the company's 40th anniversary, consisting of the name and "the memory of" the co-worker Shadi Qudsi.
Another would be:
1. Specializing a day of donation within the company, while giving out the money to the martyr's family.
2. Giving employees a day off and planning a visit to his family's house.
3. Throwing a charity event, where different activities are to be hold and donating the funds for the family's account. What ever the company chooses to do, its solutions must be creative and not expected by people.
