NEW YORK, May 20 (Reuters) - JPMorgan Chase's ( JPM )

top executives on Monday emphasized the importance of employee

health in response to a question about intense working

conditions.

A junior banker at Bank of America, Leo Lukenas III, died

from a blood clot earlier this month.

"Nothing that is more important than the health and well

being of our employees, and we're aware of those stories and

they are tragic and incredibly sad," Jennifer Piepszak, Co-CEO

of the commercial and investment bank at JPMorgan ( JPM ), told

investors.
