I'm a good employee but I can't keep up at work. How do I explain to my boss that I am overwhelmed with work and can't do any more?

I would ask are there others in your department that feel overworked as well? Did you take time off and come back to lots of work? Is it just the daily load that is too much? It may be the culture of the company. I’m trying to determine if this is your issue or the dept/company issue. Ask your boss for a progress meeting and come prepared for the meeting with your status on where you are, etc. You may ask him if you could have another member of the team help with one task that has sidelined you. I would not tell your boss that you are overwhelmed, but that you have many projects pulling at you at once and perhaps the two of you can prioritize which one you should make a priority. Always work on the tasks that your boss asked you to do first then prioritize from there.

Good luck!
