Bosses will be held to their word. If you say something, you must follow through.

Today I was sitting in my office when one
of my right-hand people came in and said “I’m going to lunch now.” I
replied, “Okay,” but somewhat indifferently because normally people in
my department do not check in with me before heading to lunch.

“I’m going to lunch because you did not get us pizza today,” she
continued. I was focusing my attention on something else, but this made
me look up.

She went on, “You said yesterday that because we were short-staffed
and had a deadline that we all pulled together on, that you might order
pizzas and have a pizza party for lunch. So I planned on having a pizza
party today and did not bring my lunch.” Whoops,  I did vaguely recalled
saying that to her, but I had forgotten until now.

I quickly said, “I’m so sorry. I completely forgot. Let me buy you lunch. Who else knows?”

“I don’t need lunch,” she quickly replied. “Just wanted to let you know.”

The experience was a reminder of this: when you are the boss you may
not remember everything that you say, but your employees do.

So be careful when you speak or make promises. You may mean things as puffery, but there is no such thing in their minds.
I have a bad habit of doing this that often gets me into trouble. A
few years ago we were at an office happy hour, and I had been enjoying
myself just a little bit too much. The subject of Las Vegas came up as a
general destination for travel. Soon thereafter we were discussing our
company’s ten-year anniversary. Well, one thing led to another and soon I
announced that we would consider a Vegas trip for our ten-year
anniversary for all employees. At the time we were a relatively small
company. In the 18 months since that original proclamation we have
quadrupled in size. And a simple alcohol-infused idea has become a
reality, and in July the entire company will be heading to Las Vegas for
our ten-year anniversary.

So I am reminded be mindful of what I say. When speaking to employees, always remember:
1. Think Before You Speak

Seems so easy, doesn’t it? But every word that comes out of
your mouth has meaning. And they will rely on it. So always make sure
you think before you speak and you consider the ramifications of any
promises or decisions before they are articulated.

2. Pull It Back Immediately

If you find yourself in a situation where you speak before you
think and you extend a promise before considering the ramifications
immediately act to pull back that promise. The longer you wait to say,
“I have rethought this” or “We cannot do that” the more push back you
will get from the persons who were to be the beneficiaries of the
promise.

3. Keep Your Word

Assuming that you make a promise and do not pull it back
immediately you must keep your word. You must satisfy the expectations
of that promise. If not, it erodes the employer-employee relationship by
infusing an element of distrust and lack of accountability.
