One that comes to mind is that at my previous job, a staffing company, management created a situation that stomped all innovation or good ideas, and was even inconsistent with the rest of the culture and policies of the company. We had one client that was absolutely terrible and flaunted all of the rules of how we ran things; unfortunately, this client was also the highest volume (i.e. they ordered the most employees weekly) and so a disproportionately large percentage of income for the company. The margins were low on this account and it was entirely volume-based; it was a miserable company to work for, so we had to staff 10 times to fill one position for more than a couple weeks due to turnover; the management at that client was petulant, rude, and borderline abusive to the employees; and, most damaging perhaps, it took complete priority and kept other accounts from growing or being serviced adequately because they threatened to leave as clients all the time, and gave absurd timeframes so they became an urgent priority multiple times a week regardless of what was going on elsewhere.
I guess to avoid this, a company would have to be more selective about identity and whom they want to work with, and diversify clients a bit more so you can “fire” the bad ones like this.
Another example was not creating a culture of discipline and results; my first time in a management role in a small marketing company I founded involved having various interns and employees to help work on our clients’ accounts. Unfortunately, I was very lax and almost had the feeling that I owed the employees and interns something, like I was constantly convincing them to stay or something; some were internally driven which was fantastic, but I think, with many, they got very little out of the experience and we certainly got very little quality work from them.
Expectations needed to be set better, and I can’t have the perspective that they are doing me a favor by doing what they are supposed to be doing.
