I have noticed that several companies offer joining bonus to a prospective employee to join early (or shall I say "immediately").

I was wondering if this is a right tradition? Is this ethical?

I see it this way -

A guy is working in Company A and he has a notice period of 30 days. if he wishes to terminate his contract/job with Company A and move to Company B he need to serve a notice period of 30 days to Company A. This is supposedly required so that he can transfer his responsibilities in a proper way to an assigned person by Company A enabling them to maintain the smooth function of the organization in his absence. However, Company B tells the guy - "If you can join us within 7 days, we are willing to pay you a joining bonus of $X.

I personally feel that it is like bribing the person to go against the separation clause of the employment agreement, so that he can pay for any financial loss (that might arise from any penalty clause) and enjoy a bonus amount - all for doing something wrong! I see this happening almost everyday.

Don’t you think this HR practice is unethical and is further rewarding people to stoop low for some quick bucks?

What do you say?
