Working under a bad tech lead can slow you down in your career, even if you are the most talented

Here’s what you should do if you're stuck with a bad tech lead:

Ineffective Tech Lead:
- downplays the contributions of their team
- creates deadlines without talking to the team
- views team members as a tool to build and code
- doesn’t trust their team members to do their jobs
- gives no space or opportunities for personal / skill development

Effective Tech lead:
- sets a clear vision and direction
- communicates with the team & sets realistic goals
- empowers you to make decisions and take ownership
- inspires and helps you achieve your career milestones
- always looks to add value by sharing their knowledge and coaching

I've always grown the most when I've worked with the latter.

But I also have experience working with the former.

If you are in a team with a bad tech lead, it’s tough, I understand.

Here’s what you can do:

➥don’t waste your energy worrying about them

➥focus on your growth and what you can do in the environment

➥focus and try to fill the gap your lead has created by their behaviors

➥talk to your manager and share how you're feeling rather than complain about the lead

➥try and understand why they are behaving the way they behave, what’s important for them

And the most important:

Don’t get sucked into this behavior and become like one!

You will face both types of people in your career:

Some will teach you how to do things, and others will teach you how not to do things!
