Recently our unit always losing things, but can’t find out the reasons, namely leadership though they found for a long time, but has been all have no result, and then in a week before our unit installed a time attendance security door, feel the effect is really good, this week we have things, no one lost we really admire this time attendance security feel, feel is more severe than the detective? Calm again, now our work is not afraid of losing things anymore, even for a time before we have some barrier between the colleague, have some mutual suspicion, also thanks to this time attendance security feel, let us can harmonious get along again, our office and returned to the laughter of the past.
