A research has found that do-gooders who do extra hours in the office or volunteer for added tasks are disliked as they make everyone else feel guilty.

It suggests people think twice before waxing lyrical about their charity work, gifts they share out, or the unwanted jobs they take on unprompted.
In tests at Washington State University the do-gooder was frequently thrown out of the wider group.
"It doesn't matter that the overall welfare of the group is better served by someone's unselfish behaviour. What is objectively good, we see as subjectively bad," the Daily Express quoted Social psychologist Professor Craig Parks as saying.
"The do-gooders are also seen as deviant rule-breakers," Parks added.
