Many years ago, I was talking to someone (online) who worked at AOL and he mentioned that he was a Team Leader. I snickered. It's such propaganda, this title of Team Leader. We all work together! Honest! And you guide us, O Leader! We're a team! It made me laugh the first time I heard it, but my laughter was met with confusion. But but but... that's my job title! Why are you laughing at my job title? I'm a Team Leader! I'm important! Yes, it seemed that the person with whom I was conversing completely bought into the title. As for me, I don't care whether you call it "Team Leader" (though that continues to make me laugh) or "manager of this little group of people". Even if you are manager of a not so little group of people, the title of Team Leader is still stupid. I don't care if it makes you feel better about your job. It's a title, and it doesn't mean much.
Not too long ago I met another person with the title of Team Leader. And he referred to the people he worked with as his team, no less. He, too, completely bought into his title without questioning why he was called Team Leader. I tried to bring up the subject. He seemed like a fairly rational guy at the time, and I thought he'd be the sort to acknowledge that it was pretty stupid but that's just how his company termed things. I was wrong. He truly believed in his title. He thought it was a badge of honour. He thought that he was special just because his title was not Assistant Manager or Sub-assistant manager. Because, y'know, being a Team Leader is so different. I mean, let's name the differences in job requirements.
1. Non-existent.
2. Non-existent.
3. Non-existent.
And that about sums it up.
People, you can call yourself Team Leader if that's what your employer insists on calling you, but remember that it doesn't mean your employer or anyone else thinks any better of you. You do the same damn job you always did. And I'll still cringe when I hear your title.
