Before responding to your questions, I want to mention that you have taken on a daunting challenge. Writing a code of conduct is in itself not easy, especially if some of the employees may not be aware of or wish to alter their negative attitude. That said, I suggest you combine foster and maintain in one brief phrase. You could, for example, write the following:
1) Foster and maintain a positive attitude.
Next, you might want to add specific suggestions of ways in which employees could demonstrate a positive attitude. These could include: Be courteous and thoughtful; help others when you can; etc. I agree your code's phrases should be brief and concise. I suggest you offer about ten points; if the list has more than ten, you run the risk that the employees might not read them.
Also, you have asked about the appropriateness of a semicolon and I am not sure where you wish to use it. In general, semicolons are used after a short sentence followed by a related one. For example, one could use a semicolon in the following example: James wanted to attend the high school's basketball game; however, I was too tired to accompany him.
Again, I admire your assuming the responsibility of crafting a code of conduct and hope my suggestions are of help. Please feel free to contact me with further questions or comments.
Sincerely yours,
Lydia V
