If you can’t handle what’s on your plate, you can’t handle it. 12 clients is a lot depending on their posting schedule and creating custom content for all of them (even with tools like Canva) can get overwhelming.
Also:
> I am stressed and overworked, putting in unpaid extra hours every day. They gave me time off for the extra hours I worked but then I get even more stressed because I run behind.
I had to learn this the hard way, stop doing unpaid work. If the workload is too much for employee, that is NOT the employee’s fault, it’s management’s. Either stay clocked in to do the work, or (my choice), clock out, let them know what’s not getting done due to time constraints, and let them worry about it.
Obviously, this is factoring in none of the personal context of your relationship with the clients, but you are being taken advantage of for those unpaid hours. It is wage theft, if you work, you are entitlted to those wages. If they won’t pay you, they’re not entitled to your work.
Overall, it sounds like they need to hire someone else. You can’t be expected (though marketers often are) to produce the same output as an entire team. Take care of yourself first, worry about the work second. The less stressed you make yourself, the better and more efficient you’ll be when you are working. It’s a positive feedback loop (and why things like the 4-day work week are taking off) that can only help.
