These types of meetings break a little with the established rules and work relationships. In addition, the drinks contribute to the tone of the celebration being uninhibited , often more than we would have liked. If we have been cultivating an image throughout the year, we cannot throw it all away for one night.
Mistakes we should not make at the company dinner

Let's look at some that I have observed over the years, and that are repeated too often:
Drinking too much is a classic. Beers before, wine with the meal and drinks after. If they take a long time to bring the food and you go with an empty stomach, the effect can be devastating, so much so that you may only remember what you did from the photos or videos that your colleagues will share on WhatsApp for the rest of the year.
This brings us to the next recommendation: it is better to have a snack at home so as not to go on an empty stomach and not eat as if there were no tomorrow . If it is a cocktail party, there may be a shortage of food, in any case, do not hoard the tortilla as if you have not eaten for years. We should not criticize the food either, either for the quantity or the quality of it.
You can make jokes and have more relaxed conversations , but within limits. We can't let things get out of hand and make fun of the boss and embarrass him . He'll still be our boss after Christmas, and there are certain things that we might find funny, but he might not. Friendly and funny, without being offensive, walks a fine line. If you're not sure where you stand, it's best not to tell certain jokes about the boss.
