The first way, truthful, do not try to reinvent the wheel and invent an excuse poizoschrenney. Remember the story Deniska Dragoon: all the secret becomes clear. There is a chance that you yourself forget what exactly "was the cause" of your tardiness and punctures at the most inopportune moment. Or you simply hand over the "good" colleagues. Therefore, if you are sure of the loyalty of his boss, tell me, how is: slept - then slept. Could not find the keys at the last moment before going out - it happens. And not blush when you say why you were late.
The second way, "good deeds master": if your cat to give birth occurred to begin at 6 o'clock in the morning, you could do nothing but sit on the poor animals and help him as much as your own. Who really nothing to think about time? If you translate grandmother across the road, your the more excusable delay: grandmother, because they go so slow. If the driver suddenly trolley headache, then you had no choice as to take his place and carry out transportation to the end of the route. Who dares accuse a short delay when you - the hero of the day?
The third way, "road": sometimes the reason for the delay actually does not depend on you. Like and came on time and even with a margin, and still have to pass reception guiltily. The main "hero" of this delay - of course, public transport. Traffic jams have an amazing ability to suddenly appear where previously they had never been. Accident, paralyzing traffic, happens all the time. This is perhaps the most common cause of delays. The main thing - do not overdo it.
Fourth way, "trudogolichny": diligent workers appreciate the heads. If present the reason for his delay, both directly related to your employment, then the punishment can not be followed. What could it be? You could sit at work until night, hurrying to make an urgent report, and a dream you have only two hours. Before you work out of town to the post office to send registered letters to customers, met with harmful supplier, who did not have time for the meeting, except in the early morning. And maybe you were deciding the transport company, due to which in the last quarter of your company suffered losses. The main thing - please be plausible confirmation of your working "feats".
Fifth way for a leader with a sense of humor: you went to work as usual, 4 hours before the start of the day. In the middle of the road bus gets into an accident and the driver breaks his leg, and even both. Remembering school first aid course, you apply it on the bus and bear arms to the nearest hospital. On the way to the hospital you see black smoke, Valya from its windows. Putting the driver on a bench in the park, you rushes to extinguish the fire and to help make the patients. Nurses in a panic, nurses tear hair. Then it all depends on your imagination and patience from your boss. Effective way, but unfortunately, you can only use it once.
